Do trivial rustdoc improvements 2023-08-01 16:30:21 +10:00
Tobin C. Harding 3225aa9556
Use defensive documentation
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.

crypto: key: Move error code to the bottom of the file
Error code is boring, put it at the bottom of the file.

Add InvalidSighashTypeError
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.

Improve error display imlps
Improve the `Error` `Display` impls by doing:

- Be more terse by importing the error enum's variants.
- Do not use capital letters for error messages.

Rename non standard sighash error type
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.

Use standard set of derives on all error types
As part of an ongoing effort to make our error types stable and useful
add a stand set of derives to all error types in the library.

    `#[derive(Debug, Clone, PartialEq, Eq)]`

Add `Copy` if possible and the error type does not include
`#[non_exhaustive]`.

If an error type includes `io::Error` it only gets `#[derive(Debug)]`.

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.

Move EncodeSigningDataResult to sighash module
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.

`sighash` module where it is used.

Pull request description:

  The `empty` constructor is mis-named for the following reasons:

  - Non-standard with respect to stdlib which uses `Path::new` and `PathBuf::new` (on which we based the `Scritp`/`ScriptBuf`)

In order to keep the embedded and schemacs test crates building when we

already has an entry.
- For `hashes/embedded` add `patch` section for `internals`.
- For `hashes/extendend_tests/schemars` add `patch` section for

Currently the test `hex` macro is only available when the `test`
compiler configuration option is set but we are using it in benches
code, this works for use because `cargo bench` sets `test` for the
current crate, however it breaks downstream crates.

Fix: #1830

Merge rust-bitcoin/rust-bitcoin#1913: Manually implement Debug on Witness
d45dbef3e7 Manually implement Debug on Witness (Tobin C. Harding)

Pull request description:

  The current derived debug implementation on `Witness` prints the content field as an array of integers. We can do better than this by manually implementing `Debug`.

  With this applied `Witness` is printed as follows: (first line is `{:?}` and the next is `{:#?}`):

  Using `{:?}`:
  ```
  Witness: { indices: 3, indices_start: 8, witnesses: [[0x00], [0x02, 0x03], [0x04, 0x05]] }
  ```

  Using `{:#?}`:
  ```
  Witness: {
      indices: 3,

Add more rustdocs to WitnessProgram
Add rustdocs to `WitnessProgram` commenting on why we carry the witness
version number around with the witness program. This is mainly a dev
comment but it helps document the invariants so make it a rustdoc
comment.

Move witness types to the script module
From BIP 141:

> A scriptPubKey (or redeemScript as defined in BIP16/P2SH) that
> consists of a 1-byte push opcode (for 0 to 16) followed by a data push
> between 2 and 40 bytes gets a new special meaning. The value of the
> first push is called the "version byte". The following byte vector
> pushed is called the "witness program".

`WitnessVersion` and `WitnessProgram` are scriptPubkey concerns and
scriptPubkey is basically synonymous with address so in one way it makes
sense that these types are in `address` however we are in the process of
overhauling the `Address` (and `AddressInner`) types so lets move the
witness stuff to `script` and put it in individual sub-modules.

This move helps simplify the address error type also.

Note please, there are a bunch of formatting changes in here in the
error type that I cannot explain and could not remove.

Rename Script::empty to Script::new
The `empty` constructor is mis-named for the following reasons:

- Non-uniform with `ScriptBuf::new`
- Non-standard with respect to stdlib which uses `Path::new` and
  `PathBuf::new` (on which we based the `Scritp`/`ScriptBuf`)

Rename the function to `new`, put it at the top of the impl block while
we are at it.

Pull request description:

  We are trying to make error types stable on the way to v1.0

  The current `hashes::Error` is a "general" enum error type with a single variant, better to use a struct and make the error usecase specific.

  Improve the `hashes::Error` by doing:

  - Make it a struct
  - Rename to `FromSliceError`
  - Move it to the crate root (remove `error` module)

  Includes usage in `bitcoin`.

Merge rust-bitcoin/rust-bitcoin#1879: embedded: Document how to clean up linker flags
3af9258025 embedded: Document how to clean up linker flags (Tobin C. Harding)

Pull request description:

  Document how to clean up.
