For the `hashes` crate we would like to make `hex` an optional
dependency. In preparation for doing so do the following:
- Remove the trait bounds from `GeneralHash`
- Split the hex/string stuff out of `impl_bytelike_traits` into a
separate macro.
The `impl_bytelike_traits` macro is public and it is used in the
`hash_newtype` macro, also public.
Currently if a user calls the `hash_newtype` macro in a crate that
depends on `hashes` without the `serde` feature enabled and with no
`serde` dependency everything works. However if the user then adds a
dependency that happens to enable the `serde` feature in `hashes` their
build will blow up because `serde` code will start getting called from
the original crate's call to `hash_newtype`.
Pull the serde stuff out of `hash_newtype` and provide a macro to
implement it `impl_serde_for_newtype`.

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.
The private_key_debug_is_obfuscated test is removed because it belongs
in the secp256k1 library, not in the bitcoin library. Keeping it here
is redundant and creates unnecessary maintenance.
As we have been doing in other places deprecate `to_bytes` in favour of
`to_vec`. Note this is only for functions that return a `Vec`, the `key`
module has `CompressedKey::to_bytes` still as it returns an array.
30bb93c676 Implement impl_to_hex_from_lower_hex macro for types that implement fmt::LowerHex (Shing Him Ng)
Pull request description:
Created a macro that implements `to_hex` for types that currently have `core::fmt::LowerHex` and called it on types that have `core::fmt::LowerHex` implemented. I put the macro in the `internals` crate since there are types across the whole project that can potentially use this.

`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.
c72069e921 Bump MSRV to 1.63 (Martin Habovstiak)
Pull request description:
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. (Accompanying PR to secp256k1: https://github.com/rust-bitcoin/rust-secp256k1/pull/709 )
Suggested plan:
* merge both PRs
* at some point release `hashes` and `secp256k`
* remove `rand-std` from `bitcoin`
* release the rest of the crates

We would like to move the `Script` type to `primitives` without moving
any key stuff, including pubkey hashes. We may later, before releasing
`primitives`, move the `WPubkeyHash` at which time this patch can be
reverted or re-implemented on `ScriptBuf`.
The `ScriptBuf::p2wpkh_script_code` function does not take `self` as a
parameter but it does return `Self` - this can trivially be made into a
standalone function.
Make `ScriptBuf::p2wpkh_script_code` a standalone function.
d099b9c195 Remove wildcard from prelude import (Jamil Lambert, PhD)
Pull request description:
This patch replaces `prelude::*` wildcard imports with the types actually used. In a couple of cases `DisplayHex` was previously imported by the wildcard but was only used in the test module, an additional import was added to the test module instead of at the top where it causes an unused import warning.

Wildcards have been replaced with what is actually used.
In a couple of cases an additional use statement was added to the test
module to import `DisplayHex` which is only used in test, but
previously imported with the wildcard at the top.
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.

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.

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.
Rust nightly as of 2024-05-27 has a new lint which detects list items
which are continued by a non-indented line. Markdown treats these as
single list items, which they sometimes are, but sometimes we intended
them to be on a separate line.
Also changes the docs for `UntweakedKeypair::tap_tweak` because the
existing ones were overly technical and out-of-date.

We are currently using the `base58::Error` type to create errors in
`bitcoin`, these are bitcoin errors not `base58` errors.
Note that we add what looks like duplicate
`InvalidBase58PayloadLengthError` types but they are different because
of the expected length. This could have been a field but I elected not
to do so for two reasons:
1. We will need to do so anyways if we crate smash more
2. The `crypto::key` one can have one of two values 33 or 34.
With this applied we can remove the now unused error variants from
`base58::Error`.

Constructing a pubkey using `PublicKey::from_slice` can fail for reasons
other than just incorrect length - we should not be using `expect` but
rather returning the error.
A purist might argue that we are now returning a nested error type with
an unreachable variant:
`ParsePublicKeyError::Encoding(FromSliceError::InvalidLength)`
Is this acceptable or do we want to further improve this?
