Add a standalone `hash` function that is a drop in replacement for
`GeneralHash::hash`. Do not add it to `hmac` - this is in parity with
the current code because `Hmac` does not implement `GeneralHash::hash`.
Use the new function in `bitcoin` removing all occurrences of
`GeneralHash` from `bitcoin`.
In `hashes` replace usage of `GeneralHash::hash` with the new `hash`
function.

During upgrade of `secp256k1` a number of function calls needed to be
rewritten to not use `from_slice` but `from_byte_array`. Unfortunately,
the conversion wasn't correct and caused panics on invalid inputs
rather than errors.
This fixes it simply by calling `try_into` on the entire slice and
converting the error.

We would like to return an error when doing math ops on amount types.
We cannot however use the stdlib `Result` or `Option` because we want to
implement ops on the result type.
Add an `AmountOpResult` type. Return this type from all math operations
on `Amount` and `SignedAmount`.
Implement `core::iter::Sum` for the new type to allow summing iterators
of amounts - somewhat ugly to use, see tests for example usage.
We want to get rid of this constant, so we replace it in tests with 0
amount, empty script. Notably, the tests were already using it as a
dummy value - the exact amount was irrelevant, so this change doesn't
break anything.

4a5b2c60c6 Use ssat variable in tests (Tobin C. Harding)
Pull request description:
We have a `_unchecked` constructor now for both `Amount` and `SignedAmount`. Soon we would like to start enforcing the `MAX_MONEY` invariant in both amount types. To make that change easier do a few refactorings:
- Patch 1 and 2 introduce local variables for amount constructors.
- Patch 3 replaces the local variables introduce in (1) and (2) with macros
- Patch 4 uses `_unchecked` constructor for hard coded integers
The strange patch separation is done intentionally so we don't inadvertently reduce test coverage by using the wrong constructor. I made this mistake already in a previous PR, lesson learned.
Note please, the macro introduced in patch 3 is in preparation for enforcing `MAX_MONEY`. The macros allow us to panic (`from_sat().unwrap()`) instead of using the `_unchecked` version.

We have a `_unchecked` constructor now for both `Amount` and
`SignedAmount`. In preparation for enforcing the `MAX_MONEY` invariant
use the `_unchecked` constructor throughout the codebase to construct
amounts from hard coded integer values.
Rust macros, while at times useful, are a maintenance nightmare. And
we have been bitten by calling macros from other crates multiple times
in the past.
In a push to just use less macros remove the usage of the
`impl_from_infallible` macro in the bitcoin, units, and internals crates
and just write the code.
There is a loose convention in Rust to not use `test_` prefix. The
reason being that `cargo test` outputs 'test <test name>' using the
prefix makes the output stutter.
This patch smells a bit like code-churn but having the prefix in some
places and not others is confusing to new contributors and is leading me
to explain this many times now. Lets just fix it.
Remove the prefix unless doing so breaks the code.
The Amount type provides better type safety and is more appropriate in
this context than u64. Currently the checked arithmetic operations for
Amount and u64 are identical in behavior. Therefore, this refactor does
not result in any behavior change and is purely cosmetic.
To prevent rounding errors converting to and from f64 change
`Amount::MAX` to `MAX_MONEY` which is below the limit in f64 that has
issues.
Add checks to `from_str_in`, `checked_add` and `checked_mul` that the
result is below MAX, where previously a u64 overflow was relied on.
Change tests to account for new lower MAX that is within the range of
SignedAmount and does not overflow so easily
Remove overflow tests
`Amount::MAX` is now below `u64::MAX` and within the range of values for
`SignedAmount`. These tests therefore do not overflow.
In effective_value there is no error with `Amount::MAX` and the correct
value is returned.
In psbt the removed test is effectively the same as the previous test.
Modify `Amount` tests to work with new `MAX`
Tests need to be changed that checked values above the new `MAX` or
`Amount::MAX` was out of range for `SignedAmount` which it isn't anymore

There is a range of different wordings used in the docs of constructor
type functions.
Change all to start with `Constructs a new` or `Constructs an empty`.
In functions that act like constructors there is a mixture of the usage
of `creates` and `constructs`.
Replace all occurrences of `creates` with `constructs` in the first line
of docs of constructor like functions.
Deprecate the `Script::to_bytes` function in favour of `to_vec` as we
are doing elsewhere.
Note that `ScriptBuf` has `into_bytes` because it does not copy.
Potentially this should be deprecated in favour of `into_vec`?
Note that in regards to the `to_` prefix this naming as valid according
to convention because the `Script` type is borrowed and `to_vec` copies
the underlying bytes.
During this release cycle we deprecated `to_vec` in favour of
`to_bytes`, we have since reversed our position on the name.
Remove the deprecation of `to_bytes` from the three types that had it
and use `to_vec`.
WARNING: This is not like all the other extension traits.
Because of the use of generics on various `Transaction` methods it is
not easily possible to use the `define_extension_trait` macro.
Manually create the extension traits (public and private) for the
`Transaction` type. This is quite ugly but c'est la vie

The `consensus::encode::Error` contains an IO error but reading from a
buffer only ever errors for EOF. We converted all instances of EOF to
`MissingData` already so now we can split the IO error apart from the
actual encoding errors variants.

public visitor types.
Recently we deprecated `to_vec` in favour of `to_bytes` however we
continued to use `to_vec` in a few places. This wasn't noticed because
of our usage of `TBD` in the `deprecated` attribute.

This change makes method names on Xpub and Xpriv more consistent and
easier to discover by following two patterns:
- if the method deals with extended key, it contains 'xpub' or
'xpriv' in its name
- if the method deals with non-extended key, it contains
'public_key' or 'private_key'
One exception is 'ckd_*' methods, which are lower-level and their names
come from BIP32; these keep using 'priv' and 'pub'.
Currently we provide `Default` implementations for a couple of types in
the `transaction` module, the values returned are meaningless and it
seems these impls were added to make writing test code easier. In
hindsight this was the wrong thing to do.
Break the API and remove the `Default` implementations for `OutPoint`
and `TxIn`.
Add an associated const `TxIn::EMPTY_COINBASE` that is, as the name
suggests, an empty transaction input with the prevout set to all
zeros as for the coinbase transaction.
At some stage we named the compact encoding `VarInt` (which makes sense
because the compact size encoding is a variable length integer encoding).
However it turns out the term "varint" is used in Core for a different
encoding so this may lead to confusion.
While we fix this naming thing observe also that the `VarInt` type is
unnecessarily complicated, all we need to be able to do is encode and
decode integers in compact form as specified by Core. We can do this
simply by extending our `WriteExt` and `ReadExt` traits.
Add `emit_compact_size` and `read_compact_size` to emit and read compact
endcodings respectively.
Includes addition of `internals::compact_size::encoded_size_const`.
Patch originally written by Steven, Tobin cherry-picked and did a bunch
of impovements after the varint vs compact_size thing (#1016).

8ec3571d80 Implement GetKey for Vec<Xpriv> (Nadav Ivgi)
Pull request description:
It appears that the `BTreeSet<Xpriv>`/`HashSet<Xpriv>` sets currently implementing `GetKey` cannot actually be constructed, because `Xpriv` does not implement `Ord` nor `Hash`. (And that the rust-bitcoin code referencing these sets should not even compile? yet evidently it does 👀 )

`s.parse` is more idiomatic and produces more helpful error messages.
This has been changed repo wide in the main codebase, not including
examples, rustdocs, and in the test module.
`use std::str::FromStr;` has been removed where this change makes
it unnecessary.
There are a couple of issues around the ECDSA signature decoding /
parsing code. We have duplicate code in `from_str` and `from_slice`
and both use the same error type even though it is impossible to get a
hex error in `from_slice`.
Create two errors:
- A `DecodeError` returned by `from_slice`
- A `ParseSignatureError` that has a decode variant and a hex variant
Call through to `from_slice` after parsing hex into a byte vector.
Removes an instance of `unreachable!`.
Fix: #1193
In preparation for moving the `ScritpBuf` type to `primitives` add a
public and private extension trait for the functions we want to leave
here in `bitcoin`.
Note, includes a change to the `difine_extension_trait` metavariable
used on `$gent` from `ident` to `path` to support the generic
`AsRef<PushBytes>`.
In preparation to move script types to `primitives` we replace impl
block with extension traits by replacing the temporary modules with
`define_extension_trait`.
We already explicitly do not support 16 bit machines.
Also, because Rust supports `u182`s one cannot infallibly convert from a
`usize` to a `u64`. This is unergonomic and results in a ton of casts.
We can instead limit our code to running only on machines where `usize`
is less that or equal to 64 bits then the infallible conversion is
possible.
Since 128 bit machines are not a thing yet this does not in reality
introduce any limitations on the library.
Add a "private" trait to the `internals` crate to do infallible
conversion to a `u64` from `usize`.
Implement it for all unsigned integers smaller than `u64` as well so
we have the option to use the trait instead of `u32::from(foo)`.
The version 1.63 satisfies our requirements for MSRV and provides
significant benefits so this commit bumps it. This commit also starts
using some advantages of the new MSRV, namely namespaced features, weak
dependencies and the ability to use trait bounds in `const` context.
This however does not yet migrade the `rand-std` feature because that
requires a release of `secp256k1` with the same kind of change - bumping
MSRV to 1.63 and removing `rand-std` in favor of weak dependency.

In the next commits we are going to stop exposing the ability to hash
arbitrary data into wrapped hash types like Txid etc. In preparation for
this, stop using these methods internally.
This makes our internal code a little bit uglier and less DRY. An
alternative approach would be to implement the from_engine and engine
methods, but privately (and maybe having a macro to provide this). But I
think this approach is more straightforward.
The one exception is for the Taproot hashes, which are tagged hashes and
currently do not have their own engine type. I will address these in a
later PR because this one is already too big.

Manually implement it for Wtxid, Txid and BlockHash, where the all-zero
"hash" has a consensus meaning. But in general we should not be
implementing this method unless we have a good reason to do so. It can
be emulated or implemeted in terms of from_byte_array.
The use of Wtxid::all_zeros is obscure and specific enough that I am
tempted to drop it. But for txid and blockhash, the 0 hash appears in
actual blockdata and we should keep it.
All other uses of all_zeros were either in test code or in places where
the specific hash was not important and [u8; 32] was a more appropriate
type.
the `blockdata` directory is code organisation thing, all the
types/modules are re-exported from other places. In preparation for, and
to make easier, the `primitives` crate smashing work - remove all
explicit usage of `blockdata`.
Note that the few instances remain as they seem required e.g.,
`pub(in crate::blockdata::script)`
Refactor only, no logic changes.
There are two limits that the Bitcoin network enforces in regard to
hashing scripts
- For P2SH the redeem script must be less than 520 bytes
- For P2WSH the witness script must be less than 10,000 bytes
Currently we are only enforcing the p2sh limit when creating an address
with `Address::p2sh`.
There are various ways to create addresses from script hashes and if
users manually hash a script then use the `ScriptHash` (or
`WScritpHash`) our APIs assume the script that was hashed is valid. This
means there is the potential for users to get burned by creating
addresses that cannot be spent, something we would like to avoid.
- Add fallible constructors to `ScriptHash` and `WScriptHash`
- Add `TryFrom` impls as well to both types
- Remove the `From` impls

Currently we have a trait `Hash` that is required for `Hmac`, `Hkdf`,
and other use cases. However, it is unegonomic for users who just want
to do a simple hash to have to import the trait.
Add inherent functions to all hash types including those created with
the new wrapper type macros.
This patch introduces some duplicate code but we are trying to make
progress in the hashes API re-write. We can come back and de-dublicate
later.
Includes making `to_byte_array`,`from_byte_array`, `as_byte_array`, and
`all_zeros` const where easily possible.
9e4b092fce psbt: Use macro instead of function (Tobin C. Harding)
Pull request description:
We have a private function that makes use of the `Hash` trait to generically hash map entries. This usage makes patching the `hashes` module difficult. We can achieve the same thing by using a macro and passing in the concrete type.
This is an internal change, no effect on logic or public API.

6ba7758b30 Improve array macros (Tobin C. Harding)
Pull request description:
Currently we have two macros used when creating array wrapper types, one is in `internals` and the other in `bitcoin::internal_macros`. It is not immediately obvious what is what and why there are two.
Improve the macros by:
- Move the inherent functions to `impl_array_newtype`
- Use `*_byte_array` for the names instead of `*_bytes`
- Re-name the other macro to match what it now does
