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.
Should help with #765
Based on #1252

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.

My local scripts did not test serde feature on merge commit. While
merging 734, I accidently broke the serde feature on latest master. This
PR fixes it.
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?
Fixes#723

`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()
