As we have recently been doing, move the declaration of the hash type to
where it is used.
Move the `XpubIdentifier` hash declaration to the `bip32` module.
This is an API breaking change.
A P2TR output does not need to be clarified with version 1, it is
implicit. As with p2wpkh/p2wsh and version 0.
Remove redundant version identifiers from function names, deprecating
the originals.
`T` is a generic that implements`AsRef<PushBytes>`, it should not be a
reference. This is inline with other usages of `AsRef<PushBytes>` for
example in `Builder::push_slice`.
One encodes to a writer and decodes from a reader, most of the time in
the consensus `Encodable`/`Decodable` traits we use generic `R`/`W` and
variable `r`/`w` but there are other places that use other characters.
While touching these lines note also that there are a bunch of unneeded
`mut`s, I'm not sure why since usually between the compiler and the
linter `mut` is handled correctly.
Make implementations of `Encodable` and `Decodable` uniform by:
- Use R/W and r/w for trait and variable name
- Remove unneeded mut
Done as part of the push to have small specific errors instead of large
general ones.
Split the `witness_version::Error` up into small specific errors.
Recently we "if" guarded subtraction manually using `> 0`, we can better
convey the meaning by using `checked_sub` and pattern match on the
option.
Refactor only, no logic changes.
Recently we deprecated the `segwit_signature_hash` function but during
development the deprecation notice got stale.
Fix deprecation notice to use the actual function names.

Pull request description:
When we introduce a custom `Debug` implementation for the `Witness` we introduced a bug that causes code to panic if the witness contains an empty instruction.
The bug can be verified by putting patch 2 first or by running `cargo run --example sighash` on master.

We currently have a bunch of functions that are infallible if the
`index` argument is within-bounds however we return a `SignError`, this
obfuscates the code.
Add an `IndexOutOfBoundsErorr`. While we are at it make it an enum so
users can differentiate between which vector the out of bounds access
was attempted against.
Throughout the codebase we cast values to `u64` when constructing a
`VarInt`. We can make the code marginally cleaner by adding `From<T>`
impls for all unsigned integer types less than or equal to 64 bits.
Also allows us to (possibly unnecessarily) comment the cast in a single
place.
The `ThirtyTwoByteHash` trait is defined in `secp256k1` and used in
`hashes` as well as `bitcoin`. This means that we must use the same
version of `hashes` in both `bitcoin` and `secp256k1`. This makes doing
release difficult.
Remove usage of `ThirtyTwoByteHash` and use `Message::from_slice`.
Include TODO above each usage because as soon as we release the new
version of secp we can use the new `Message::from_digest`.
This is step backwards as far as type safety goes and it makes the code
more ugly as well because it uses `expect` but thems the breaks.
BIP-32 defines 4 4-byte consts used as version bytes; currently we are
hardcoding the version bytes in multiple places.

Currently if the witness has zero elements or any of the individual
witnesses is empty we panic. Panic is caused by subtracting 1 from a
zero length.
Check the length is non-zero before subtracting 1, print `[]` if empty.

f3412325ea weight: Make docs uniform and terse (Tobin C. Harding)
Pull request description:
- Patch 1 is docs cleanup
- Patch 2 adds two functions to `FeeRate`
From the commit log of patch 2:
Calculating the absolute fee from a fee rate can currently be achieved
by creating a `Weight` object and using
`FeeRate::checked_mul_by_weight`. This is kind of hard to discover, we
can add two public convenience functions that make discovery of the
functionality easier.
Add two functions for calculating the absolute fee by multiplying by
weight units (`Weight`) and virtual bytes (by first converting to weight
units).
This seems like an obvious thing so I'm inclined to think that Kixunil left it out for a reason. (Mentioning you here Kix so even if this merges you'll see it in notifications later on.)

EDIT: The commit hashes below are stale but the text is valid still.
In an effort to "perfect" our error handling, overhaul the error handling in the `crypto` module.
The aim is to do a small chunk so we can bikeshed on it then I can apply the learnings to the rest of the codebase.
Its all pretty trivial except:
- commit `4c180277 Put NonStandardSighashTypeError inside ecdsa::Error variant`
- comimt `5a196535 Add InvalidSighashTypeError`
- commit `05772ade Use defensive documentation`
Particularly the last one might be incorrect/controversial.
Also, please take the time to check the overall state of error code in the `crypto` module on this branch in case there is anything else we want to do.

Improve the script hash types by doing:

- Put the From impls directly below the type definitions
Keep the current crate level re-export so this does not impact the

The `ServiceFlags` type is used by the p2p layer. It can live in the

`p2p::constants` module.
This is a straight code move, the `ServiceFlags` replaces the

The `network` module deals with data types and logic related to
internetworking bitcoind nodes, this is commonly referred to as the p2p
layer.
Rename the `network` module to `p2p` and fix all the paths.
Only commit in the docs and error messages to what we _really_ know.
In an attempt to reduce the likelyhood of the code going stale only
commit to what is guaranteed - that we have an error from a module.
This does arguably reduce the amount of context around the error.
As we do for `NonStandardSighashErrorType` add an error struct for
invalid sighash type, used by the `taproot` module instead of returning
a generic error enum with loads of unused variants.
Error types conventionally include `Error` as a suffix.
Rename `NonStandardSighashType` to `NonStandardSighashTypeError`.
While we are at it make the inner type private to the crate, there is no
need to leak the inner values type.

5c8933001c Avoid serialize inner data in RawNetworkMessage (Riccardo Casatta)
bc66ed82b2 Impl Encodable for NetworkMessage (Riccardo Casatta)
8560baaca2 Make fields of RawNetworkMessage non public (Riccardo Casatta)
Pull request description:
This PR removes the need to serialize the inner NetworkMessage in the RawNetworkMessage encoding, thus saving memory and reducing allocations.
To achieve this payload_len and checksum are kept in the RawNetworkMessage and checksum kept in CheckedData, to preserve invariants fields of the struct are made non-public.

This type was defined in the `transaction` module because it was
originally used in a function that had been deprecated in favour of
moving the logic to the `sighash` module.
We just removed the deprecated code so we can now move this type to the
`sighash` module where it is used.
We only keep deprecated code around for one release so we can now remove
code deprecated in v0.30.0
Done in preparation as we gear up for v0.31.0 release.
RawNetworkMessage keep the payload_len and its checksum in the struct, thus
is not needed to serialize the inner network message
pub in fields of both RawNetworkMessage and CheckedData are removed so that
invariant are preserved.
