The rust version is supposed to be set by the build script so that users
automagically get features matching the toolchain in use. Currently we
have a feature in the manifest for `rustv_1_53` instead setting a
compiler conditional configuration option in the build script. This
causes `cargo +1.41.1 --all-features check` to fail.

Pull request description:
This work started out, as the branch name suggests, as an effort to use the `hex_lit` crate. But once I got to this stage it seems that the `hex!` macro we have provides different, useful, functionality than the `hex_lit::hex!` macro (it allows usage with non-consts). So I'm unsure if we want to remove it now.
- Patches 1 - 6 are preparatory clean ups
- Patch 7 reduces usage of `FromHex`, please see git log for full description
- Patch 8 removes `hex_from_slice` and fixes a bug in how we display `Sighash`

`Sighash` should be displayed forwards according to BIP143. Currently we
are displaying it backwards (as we do for double SHA256). This is
working because parse using `Vec::from_hex`.
We have the means to parse hex strings directly for hashes, we no longer
need `hex_from_slice`.
BIP143 test vectors display double SHA256 forwards but we display
backwards, this is acceptable because there is no fixed display in the
ecosystem for double SHA256 hashes. In order to overcome this we parse
test vector hex strings with into `Vec` when needed.
Remove `FromHex` from hash and script types
- Remove the `FromHex` implementation from hash types and `ScriptBuf`
- Remove the `FromStr` implementation from `ScriptBuf` because it does not
roundtrip with `Display`.
- Implement a method `from_hex` on `ScriptBuf`.
- Implement `FromStr` on hash types using a fixed size array.
This leaves `FromHex` implementations only on `Vec` and fixed size arrays.
In preparation for modifying some unit test data structures, manually
format the code so it is uniform.
Move elements added to a vec with `vec!` onto a new line so they all
line up and one can better see what fields go where.
Refactor only, no logic changes.

The `max_value` and `min_value` functions only exist to be
compatible/uniform with Rust 1.41.1 they will never change and they just
return a constant value. They can therefore be made const functions.
Recently we merged `commit 53d4fe66b57c255086def2b5e47afaddee776b75` to

reading the code (shows that the bit stream writer is not writing from a

Add back in the `'_` (I forget what its called).

Currently we are using a `Sighash` which wraps double sha256 so while technically correct this means we are relying on `Sighash` to implement `Encodable`. We can remove this requirement by directly using the `sha256d::Hash` type to hash the outputs data.

e7bbfd3913 Improve Psbt error handling (DanGould)
Pull request description:
## Separate `encode::Error` and `psbt::Error` recursive dependency
This initial work attempts to fix#837's first 2 points
> - The current psbt::serialize::Deserialize has an error type of consensus::encode::Error. I think we should cleanly separate consensus encoding errors from application-level encoding errors like psbt.
> - There is a recursive dependence between encode::Error and psbt::Error which would need to be cleanly dissected and separated so that there is no dependence or only one-way dependence.
## Better `ParseError(String)` types
arturomf94 how compatible do your #1310 changes look to address #837's third point with this design?
> - There are a lot ParseError(String) messages that could use a better type to downflow the information.
I think your prior art would completely address this issue now.
## On handling `io::Error` with an associated error
`encode::Error` has an `Io` variant. now that `Psbt::deserialize` returns `psbt::Error` and produces an `io::Error`, we need an `Io` variant on `psbt::Error`. Except that doing so breaks `#[derive(Eq)]` and lots of tests for `psbt::Error`.
Kixunil, I'm trying to understand your feedback regarding a solution to this problem.
> I believe that the best error untangling would be to make decodable error associated.
> I meant having associated `Error` type at `Decodable` trait. Encoding should only fail if the writer fails so we should have `io::Error` there (at least until we have something like `genio`).
>
> > [it] is a problem to instantiate consensus::encode::Error in [the psbt] module for `io::Error`?
>
> It certainly does look strange. Maybe we should have this shared type:
>
> ```rust
> /// Error used when reading or decoding fails.

Kixunil didn't we just get rid of Psbt as `Decodable`? Would this make more sense to have as an error associated with `Deserialize`? Or did we do the opposite of what we should have by making Psbt only `Serialize`/`Deserialize` because of #934, where only consensus objects are allowed to be `Decodable`? I wonder if we prioritized that strict categorization and are stuck with worth machinery because of it. My goal with #988 was to get to a point where we could address #837 and ultimately implement PSBTv2.

ebfbe74243 Implement `Debug` for generic `Address<V: NetworkValidation>` (Jiri Jakes)
Pull request description:
Previously `Debug` was implemented for both `Address<NetworkChecked>` and `Address<NetworkUnchecked>`, but not for cases when the `NetworkValidation` parameter was generic. This change adds this ability. Based on Kixunil's tip.
With previous implementation, the `test_address_debug()` resulted in error:
The added `Debug` on `NetworkChecked` and `NetworkUnchecked` are required by compiler.
---
While dealing with derives and impls, I also attempted to turn all the derives on `Address` into manual impls (see Kixunil's suggestion in https://github.com/rust-bitcoin/rust-bitcoin/pull/1489#discussion_r1052448057). The motivation behind this was the possibility to remove derives on `NetworkChecked` and `NetworkUnchecked`, too. However, even with manual impls, all the traits on `NetworkChecked` and `NetworkUnchecked` were still required by compiler in this sort of situations (see also the rest of the same discussion linked above). I do not fully understand why, perhaps limitation of this way of sealing traits?
It can be demonstrated by removing `Debug` derivation on `NetworkUnchecked` and `NetworkChecked` in this PR and running `test_address_debug()`.
Therefore, if we want to allow users of the library to define types generic in `NetworkValidation` and at the same time derive impls, it seems to me that `NetworkChecked` and `NetworkUnchecked` will have to have the same set of impls as `Address` itself.

[1] commit: `c93a70487f81a93c7d479ae046c75590d9fb7733 Add client side block filter (BIP158) (#281)`
The term "final" is an archaic Bitcoin term however it is well used, it
exists in Bitcoin Core code as well as in various bips. To help folks
new to Bitcoin add documentation to the `is_final` method including
historical notes.
The `bip158` module uses a `HashSet` and in order to do so requires the
`hashbrown` dependency for "no-std" builds.
We can replace the usage of `HashSet` with a `BTreeSet` in `bip158` and
remove the `hashbrown` dependency entirely.
This patch makes no claims about performance cost or benefit of this
change. The patch also makes no claims about the validity of the current
`HashSet` usage.
The `hashbrown` dependency and `HashSet` usage can be trivially added
back in if someone comes up with perf data to back it up.
Previously `Debug` was implemented for both `Address<NetworkChecked>`
and `Address<NetworkUnchecked>`, but not for cases when the
`NetworkValidation` parameter was generic. This change adds this
ability.
In preparation for deprecating the `is_final` method; move the
`enables_absolute_lock_time` method to be directly above the `is_final`
method.
Refactor only, no logic changes.
`Sighash` does not need to implement `Encodable` because it is
claimed (I don't know exactly myself) that `Sighash` is never consensus
encode in Bitcoin.
We are currently relying on `Sighash` to implement `Encodable` when
encoding creating the segwit v0 sighash for a single input.
For reference, from BIP143:
If sighash type is SINGLE and the input index is smaller than the
number of outputs, hashOutputs is the double SHA256 of the output
amount with scriptPubKey of the same index as the input;
We can use `write_all` directly to write the hashed bytes and remove the
implementation of `Encodable` from the `Sighash` type.
While we are at it, use `write_all` to write the zero hash also to make
the code more uniform and understandable.

testing is never done - add more `mutate` attributes and add unit tests
to ensure all mutants are killed.
Of note, the `from_compact` and `to_compact_lossy` functions are not
done, doing so results in a bunch of surviving mutants.
Parsing addresses from strings required a subsequent validation of
network of the parsed address. However, this validation was not
enforced by compiler, one had to remember to perform it.
This change adds a marker type to `Address` that will assist the
compiler in enforcing this validation.

The `ToHex` trait was replaced by either simple `Display`/`LowerHex`
where appropriate or `DisplayHex` from `bitcoin_internals` which is
faster.
This change replaces the usages and removes the trait.

The additional `use` items were added to improve the style of
documentation. Because they were only used for doc they were `cfg`ed.
But because this is independent from being built by `docs.rs` the `cfg`
should've been `doc` not `docsrs`.
IOW `docsrs` means roughly `all(doc, nightly)` and the added items are
unrelated to `nightly`.

Pull request description:
This is potentially a controversial PR, but hear me out. My argument is that right now `absolute::LockTime` and `PackedLockTime` are basically identical types; they can be converted between each other with `From` and they have exactly the same semantics except that `PackedLockTime` has `Ord` on it. This makes it very confusing to tell which one should be used, for example in PSBT2 where there are now extra locktime-related fields.
The motivation for having `PackedLockTime` independent of `LockTime` are:
* `PackedLockTime` is theoretically more efficient because you don't need to unpack the field, don't need to store a enum discriminate, etc. I don't buy this. If you are trying to save individual bytes in your transaction-parsing there are lots of places you'd look before messing around with locktimes, so we shouldn't privilege this specific thing.
* `PackedLockTIme` has an `Ord` impl, and removing that will have a cascading effect on transactions, blocks, etc., preventing them from being held in `BTreeMaps` etc. **My proposal**, implemented here, is to just manually impl `Ord` on `Transaction` and don't impl it on `LockTime`.
I recall some argument that we need to be able to sort miniscripts, and miniscripts might have locktimes in them, but I think this is wrong -- miniscripts always have explicitly either a `Height` or a `Time`, and there is no problem ordering these.

b7a84d0c68 hashes: Do not implement Deref (Tobin C. Harding)
Pull request description:
Currently we implement `Deref` for hashes. From the docs [0]
> Deref should only be implemented for smart pointers to avoid confusion
Furthermore because we implement `Deref` as well as implement `internals::hex::display::DisplayHex` for slices hashes get coerced into slices and `to_lower_hex_string` can be called on them, this is incorrect because `DisplayHex` does not account for hashes that display backwards so we end up with the wrong string.
This is an API breaking change, and I have not built any other crates in our stack to check if anything breaks.

This still has the line
let lock_time = absolute::LockTime::from_height(psbt.unsigned_tx.lock_time.to_consensus_u32() + lock_time_delta).unwrap();
I'm unsure whether this "adding height to a locktime" concept is a
meaningful thing or just the sort of thing that shows up in example
code. Maybe we should have first-class support for it.
Note that the line, as written, depends on the fact that the original
locktime was a small blockheight. A proper function for this would
handle the exceptional case gracefully.
Currently we implement `Deref` for hashes. From the docs [0]

e00dfa9806 impl FromHexStr for structs with single u32 member (connormullett)
Pull request description:
Closes: #1112
- Adds new trait `FromStrHex` with 2 methods: `from_hex_str` and `from_hex_str_no_prefix`
- Impl new trait on each tuple struct with single u32 member. eg `Time(u32)`
As stated in the issue, grep through codebase with `\(u32\)` and `\(pub u32\)` to see all implementations and verify none were missed.
NonStandardSighashType is an error type and should never be constructed from a hex string. Therefore, it has been omitted from this change.
Tests are somewhat redundant, but cover 4 cases each. 2 happy paths, 1 for each function. 1 case for malformed/invalid hex input, and 1 for calling no_prefix without a prefix

Adds new module `string` to be later converted to its own
crate. The module currently contains the FromHexStr trait and an error
type to be used for implementing hex parsing on types. This change
also adds implementations of FromHexStr for types with a single u32
member such as `Sequence(pub u32)`. All structs that match the
following regex have been given this implementation
`\(u32\)` and `\(pub u32\)`. All implementations have associated
unit tests matching all possible cases. NonStandardSighashType has
been ommitted from this change as it is an error and should not be
constructed using the methods added in this change.
Adds parse::hex_u32 for future use to be made generic to allow
different sizes of integers to be parsed from hex strings.
The error type FromHexError implements required traits such as
Display and std::error::Error
d7006ef80d Adds roundtrip tests for Network::from_core_arg (Sergi Delgado Segura)
bd1eb29f61 Adds Network::to_core_arg (Sergi Delgado Segura)
Pull request description:
Comming from https://github.com/rust-bitcoin/rust-bitcoincore-rpc/pull/247
`Network::from_str` only considers `rust-bitcoin` string as possible inputs to create a `Network` instance. This PR adds a new method to `Network`, `from_core_arg`, which is complementary to the existing `Network::to_core_arg`. This method allows the conversion between `bitcoind -network` string and `Network` variants.
This also links `Network::from_str` to `Network::from_core_arg` so the default case on the former calls the latter, and an error is only returned if none of the cases match.

Recently we (tcharding) do some mechanical improvements to the rustdocs
in the `blockdata` module without considering the content. On review a
bunch of improvements were suggested.
Improve the content of various rustdoc comments in the `blockdata`
module.
Suggested content came from reviewers, all mistakes are my own :)
Reduce the number of lines of code by using a longer column width, 100
as is more-or-less standard in this repo.
This patch only changes column width (line length), no other changes.
Manual parsing Json is tedious and error-prone. It contained a bunch of
`unwrap`s and was hard to read.
This replaces manual Json parsing with serde_derive implementation.
Closes#1231
1a2cf2681d Implement consensus encoding adapter for serde (Martin Habovstiak)
a6ecc58a5e Add `put_bytes_min` and `space_remaining` methods (Martin Habovstiak)
Pull request description:
In some protocols it is preferred to serialize consensus-encodable types
using consensus encoding. E.g. serialize `Transaction` as hex-encoded
string in Json in Bitcoin Core RPC protocol. This change provides
adapter to make this easier.
The adapter allows providing custom byte-to-string encoder for more
exotic cases and provides a hex implementation which should be useful in
majority of the cases.

df90c50242 Add log2 to Work (Jiri Jakes)
Pull request description:
Adds method `Work::log2()` providing value equivalent to Bitcoin Core's `log2_work` in its logs. Fixes#1326.
Questions:
- The original issue (#1326) also suggests to add log2 to Target but it does not seem to be meaningful, does it? Bitcoin Core, to which the issue refers, also displays only log2 of work.
- Although work should not be 0, the type allows it. In this case, log2 would return -inf. I think we could leave it like that but if there are suggestions to deal with it in a different way, please let me know.

13d94cbc47 Remove no_run (Tobin C. Harding)
Pull request description:
`no_run` is not needed since we already mark this up as `bash` which rustc doesn't run when running examples.
While the keyword `bash` is not currently supported it may well be in the future and since only the `rust` keyword causes code to run any other string is effectively a wildcard, `no_run` is therefore meaningful only as a convention. Lets keep `bash` in case support is added later on.

962abcc963 Add serde regression tests (Tobin Harding)
Pull request description:
Attempts to add regression tests for _all_ types defined in `rust-bitcoin` that implement `Serialize`/`Deserialize`.
- Add a `tests` directory and implement regression tests in there
- Use files for input hex and output bincode to reduce source file clutter
- Copy test block and `include_bytes!` usage from RCasatta's [PR](https://github.com/rust-bitcoin/rust-bitcoin/pull/750)
- Uses Kixunil's macro suggested below
- Adds a single regression test to `util/taproot.rs` for private types
## Note to reviewers
- Uses JSON for opcodes in a separate file (`tests/regression_opcodes.rs`), for all other tests uses bincode.
- Bypasses the order issue for maps by only serializing maps with a single element - is this correct?

`no_run` is not needed since we already mark this up as `bash` which
rustc doesn't run when running examples.
While the keyword `bash` is not currently supported it may well be in
the future and since only the `rust` keyword causes code to run any
other string is effectively a wildcard, `no_run` is therefore meaningful
only as a convention. Lets keep `bash` in case support is added later on.
In preparation for removing the `util` module move the `base58` module
to the crate root. This is likely not the final resting place for this
module but it is a step in the right direction.
Includes addition of rustfmt attribute to skip formatting the digits
array. No other changes to the `base58` module.
For some applications, such as block explorers, it's useful to be able
to obtain the public key used in case of P2PK. This is considered
general enough for addition into bitcoin library,
so this change adds it.
The public key is returned only when it's valid and the script is P2PK.
To avoid duplicating the logic checking whether a script is P2PK the
logic is moved to a new p2pk_pubkey_bytes() method which returns raw
bytes and is then called from both is_p2pk() and p2pk_public_key()
We are trying to flatten the `util` module. The `taproot` module can
live in the crate root. If/when we create a `crypto` module/crate we may
wish to pull some stuff out of this module but for now moving it gets us
closer to removing `util` without making the directory structure any
worse.
Includes adding rustfmt attributes to skip formatting of macros.

Kani can't really handle string processing, and appears to be unable
to check integer multiplication (for now), but we do several checks
for addition and subtraction, and conversion between signedness,
that Kani can easily prove.
Done as part of flattening util.
Currently in `util` module we have a bunch of modules that provide
cryptography related functionality.
Create a `crypto` module and move into it the following:
- ecdsa
- schnorr
- key
To improve uniformity and ergonomics, do the following re-names while we
are at it:
- EcdsaSig -> ecdsa::Signature
- SchnorrSig -> schnorr::Signature
- EcdsaSigError -> ecdsa::Error
- SchnorrSigError -> schnorr::Error
- InvalidSchnorrSigSize -> InvalidSignatureSize (this is an error enum variant)

Amount of coins available stay in the same across Bitcoin network:
signet, testnet, mainet. From my understanding this is a leftover
from some potential multi-chain support.
We just removed the `bitcoin/src/network/` exclude from `rustfmt` config
file. Run the command `cargo +nightly fmt`.
No other changes than those introduced by `rustfmt`.
When we moved to edition 2018 the use of `extern` became unnecessary and
we moved to using `pub use` for re-exports. It was observed however that
`pub extern crate` is more readable.
Improve crate root re-exports by doing:
- Use `pub extern crate foo` to re-export foo.
- Fix docs attribute for optional dependency `bitcoinconsensus`.
- Re-order to how rustfmt would put them.

Remove the non-functional deprecated lines and elect to _not_ re-export things we moved. Release 0.30 is going to break a lot of code but there is no real nice way to resolve that. We will need good release notes and a public apology probably :)
Fix import statements that still rely on `util::bip32` - these should have been fixed when we moved the `bip32` module.

out of the util module. Turns out while the code reads like it works,
`deprecated` actually only works for functions, not types or modules

We would like to bring the `bitcoin_hashes` crate into the
`rust-bitcoin` repository.
Import `bitcoin_hashes` into `rust-bitocin/hashes`, doing so looses all
the commit history from the original crate but if we archive the
original repository then the history will be preserved. We maintain the
same version number obviously and in the changelog we note the change of
repository.
Commit hash that was tip of `bitcoin_hashes` at time of import:
commit 54c16249e06cc6b7870c7fc07d90f489d82647c7
Includes making `embedded` and `fuzzing` per-crate i.e., move them into
`bitcoin` as hashes includes these also.
NOTE: Does _not_ enable fuzzing for `hashes` in CI.
Notes on CI:
Attempts to merge in the github actions from the hashes crate however reduces
coverage by not running hashes tests for beta toolchain. Some additional
work could be done to improve the CI to increase efficiency without
reducing coverage. Leaving for another day.
3c0d5aed73 Add get_tapscript to Witness (junderw)

[Add Index<usize> and nth(index) to Witness](4226d60205)
[4226d60](4226d60205)
Arbitrary indexing into Witness fixes the API of last and second_to_last to be more flexible.
This patch started off as an addition of third_to_last, but ended up evolving
into arbitrary indexing to allow for future use cases.
A list of the indices of the start byte for each witness element is stored as an ordered
contiguous group of u32s represented as 4 bytes each in the Vec<u8> contents.
The bytes are stored using to_ne_bytes for performance reasons. A helper function is added
to the tests to allow for easier contruction of the contents Vec in test vectors. u32 was
chosen because 22 bits are needed to store 4,000,000 which is the maximum weight limit for
a block. This might need to be reworked in the event of consensus limits increasing, but
u32 can hold 1000x the current limit, so it should be fine for the forseeable future.
The push and consensus_deserialize functions utilize rotate_left and rotate_right to move
the indices to the end of the new allocation. Depending on the size of the data, this
might be more of a performance hit than just allocating a new temporary Vec to store the
indices and append them after parsing is completed. However, for a majority of cases
rotating the indices should be faster. Suggestions to use VecDeque instead of Vec for
contents necessitate other considerations, since it is not a public facing change,
those optimizations can be dealt with in future patches.
The Index<usize> trait is implemented using the new nth method with expect.
The Iter struct is reworked to make use of the new data representation. This new data
structure makes it trivial to implement DoubleEndedIterator and other such traits, but
I have decided to leave this as out of scope for this patch.

[Add get_tapscript to Witness](a7501d9599)
[a7501d9](a7501d9599)
This new method will check the last witness element to see if it starts with 0x50, and
depending on the result it will return the second to last or third to last witness
element according to BIP341.
In its current state, Witness can not know what type of script it is fulfilling,
so it is up to the caller to verify if the previous output is a taproot output or not.
---
Edit: This is the previous PR body:
> In a taproot script payment with annex, quick access to the 3rd to last element (which is the actual script in this case) is convenient.
>
> This feels like kicking the can down the road again, but I think it's a nice to have method.
>
> RCasatta dr-orlovsky were discussing this issue. I would like to ask if they have any thoughts on the addition of this.

The `Version` type uses a signed 32 bit integer inner type but we bit
twiddle as if it was a `u32`. We recently made the inner type private to
hide the data type because of this oddness.
Add methods `from_consensus` and `to_consensus` to facilitate any
possible thing users may want to do with a consensus version value.
The Bitcoin block version is a signed integer for historical reasons,
but we bit twiddle it like an unsigned integer and during consensus
encode/decode we cast the signed value to an unsigned value.
In order to hide this confusion, make the inner value private and add a
couple of constants for v1 and v2 block versions.
Currently the types in the block module have longer names than
necessary, "header" and "version" identifiers contain the word "block",
this is unnecessary because we can write `block::Header` instead of
`BlockHeader` when context is required. This allows us to use the naked
type `Header` inside the `block` module with no loss of clarity.
We are stuck with `BlockHash` because the type is defined along with all
the other hash types in `hash_types`, leave it as is for now but
re-export it from the `block` module to assist in putting types that are
used together in scope in the same place, making import statements more
ergonomic.
The `all` module enables usage of a wildcard import statement without
muddying the scope with any other types defined in `opcodes`, in other
words if one wants to use the `All` type `opcodes::All` is the most
clear way to use it, however usage of naked `OP_FOO` types is perfectly
clear.
Add documentation stating that we guarantee to never put anything else
in the `all` module so folks are confident using a wildcard import will
not bring any rubbish into scope.
Expected usage in downstream applications that need types in `opcodes`
as well as the opcodes:
```
use bitcoin::opcodes::all::*;
use bitcoin::opcodes;
```
Also, we do no implement `Ord` or `PartialOrd`, document this including
HTML tags hiding an example bug from Bitcoin Core that shows why not.

b6f9e47dba Fix `no_std` when `bitcoinconsensus` is enabled (Martin Habovstiak)
Pull request description:
`default-features = false` was missing previously but blindly adding it would lead to subtle risk of breaking when a crate not needing `std` depends on `bitcoinconsensus` and simultaneously another crate not needing `bitcoinconsensus` depends on `std` and another crate depends on them both.
This change fixes it by introducing `bitcoinconsensus-std` feature flag and provides a fallback if the flag is off. Unfortunately the fallback has to use a bit of reasonable `unsafe` due to limitations of upcasting.
The only safe alternatives are not do it and provide worse experience for crates that are affected by the problem above or break the API, which couldn't be backported and would be more annoying to use.
Closes#1343
This is considered PoC PR as I realized the possibility of the hack (and necessity of `unsafe`) at the last moment. Things like tests and modifying CONTRIBUTING to change the stance on `unsafe` will be added if `unsafe` is ACKed.

2. Change function names to `calculate[_inline]` so usage becomes `merkle_root::calculate`

In order that we can safely change/maintain de/serialization code we
need to have regression tests with hard coded serializations for each
type that implements serde.
It is enough to test a single serde data format, use JSON for `opcodes`
and bincode for other types.
Do regression testing in a newly added `tests` module.
The `base58` module is for encoding and decoding, it makes sense for the
public functions to be called `encode` and `decode`. We also have some
functions that operate on data with a checksum, for these it makes sense
to tack `check` onto the _end_ of the function name.
With this applied the public API is:
- decode
- decode_check
- encode
- encode_check
- encode_check_to_fmt
Code is arguably easier to read if the most important stuff comes first.
In the old days, when writing C, we had to put definitions before they
were used but in Rust this is not the case
Re-order the `base58` file so that the public API functions are up the top
then other helper functions are defined _after_ they are called.
Refactor only, no logic changes.
Currently we are manually adding `0x` in calls to `write!`, this is
unnecessary since the alternate form already adds the `0x`.
Was verified with
```
#[test]
fn bad_checksum_error_hex_format() {
let want = "invalid base58 character 0xab";
let got = format!("{}", Error::BadByte(0xAB));
assert_eq!(got, want)
}
```
Use alternate form to print hex.
The key related errors are incorrect because they are circular, we have
a base58 error variant in `key::Error` and two key error variants in
`base58::Error`.
Remove the key errors from the `base58::Error` type.
The function call `calculate_root_inline` calculates the merkle root
using the input array as a scratch buffer, i.e., we trash the data
during recursive calls to `merkle_root_r`.
Add explicit documentation to the function so its super clear not to use
the hashes again after calling this function.
Recently we renamed the `hash` module to `merkle_root`, this makes the
public functions provided stutter if used with one layer of path as is
Rust convention:
`merkle_root::bitcoin_merkle_root`
We can improve on this by renaming the functions to 'calculate', then we
get
- `merkle_root::calculate()`
- `merkle_root::calculate_inline()`
The `util::hash` module provides two functions for computing a merkle
root from a list/iterator of hashes.
Rename the module to `merkle_root` and move it to the crate root,
deprecate the original functions.
Done as part of flattening the `util` module.
