These lints are valuable, lets get at em.
Changes are API breaking but because the changes make functions consume
self for types that are `Copy` downstream should not notice the breaks.
The `Amount` and `SignedAmount` were not supposed to implement `serde`
traits by design because doing so implicitly uses sats. We provide two
modules `as_sat` and `as_btc` to allow users to explicitly serialize in
their preferred format.
In commit: `d57ec019d5 Use Amount type for TxOut value field` derives
were added for `serde` and we did not notice it during review.
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.
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
(Includes two in the `transaction` module and one in the
`consensus_validation` module.)
We had an initial go at this but we didn't do the `Hash` trait method.
In order to do so we need to hack the serde code a fair bit, note the
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.
Use `to_bytes` instead of `to_vec`.
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.
46386337b0 Ignore doc compile error (Jamil Lambert, PhD)

With the stricter doc tests required to pick up unused imports etc. the
`compile_fail` tag also creates an Error.
Changed `compile_fail` to `ignore` to remove the Error.
Examples in documentation are not linted in the same way as other code,
but should still contain correctly written code.
unused_imports in docs have been removed in bitcoin, and a warn
attribute added to lib.rs.
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.
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
Recently we made it so that wrapper types created with `hash_newtype`
were not general purpose hash types i.e., one could not easily hash
arbitrary data into them. We would like to do the same for tagged
wrapped hash types.
In `hashes` do:
- Create a new macro `sha256t_tag` that does just the tag/engine stuff
out of the `sha256t_hash_newtype` macro.
- Deprecate the `sha256t_hash_newtype` macro.
In `bitcoin` do:
- Use a combination of `sha256t_tag` and `hash_newtype` to create tagged
wrapped hash types.
Note that we do not add private helper functions `engine` and
`from_engine` to the tagged wrapper types as we do for legacy/segwit in
`sighash`. Can be done later if wanted/needed.

Pull request description:
Similar to #3155 but for `ScriptBuf`, however it is a little more involved.
Note:
- the change to use `impl` syntax (and addition of #3179)
- mad trickery of `ScriptBufAsVec` (props to Kix)
- widening of scope of private functions
Onward and upward!

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>`.
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.
Done in preparation for moving the script types to `primitives`.
The script types have a bunch of functionality to support scriptPubkeys,
and scriptPubkeys are an address thing.
Create a module under `address` and in it create a bunch of extension
traits to hold all scriptPubkey functionality.
Includes adding an ugly-as-hell macro to create the traits.
Currently we are using a type alias for the `sha256d::HashEngine`.
Type alias' allow for potential mixing of types, a `sha256d::HashEngine`
struct can better serve our users with not much additional complexity or
maintenance burden.
