Merge rust-bitcoin/rust-bitcoin#1873: Improve `hashes::Error`
06afd52a12 Improve hashes::Error (Tobin C. Harding)

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`.

Status

Bitcoin Hashes Library

This is a simple, no-dependency library which implements the hash functions needed by Bitcoin. These are SHA1, SHA256, SHA256d, SHA512, and RIPEMD160. As an ancilliary thing, it exposes hexadecimal serialization and deserialization, since these are needed to display hashes anway.

Documentation

Minimum Supported Rust Version (MSRV)

This library should always compile with any combination of features on Rust 1.48.0.

To build with the MSRV you will need to pin serde (if you have either the serde or the schemars feature enabled)

# serde 1.0.157 uses syn 2.0 which requires edition 2021
cargo update -p serde --precise 1.0.156

before building. (And if your code is a library, your downstream users will need to run these commands, and so on.)

Contributions

Contributions are welcome, including additional hash function implementations.

Githooks

To assist devs in catching errors before running CI we provide some githooks. If you do not already have locally configured githooks you can use the ones in this repository by running, in the root directory of the repository:

git config --local core.hooksPath githooks/

Alternatively add symlinks in your .git/hooks directory to any of the githooks we provide.

Running Benchmarks

We use a custom Rust compiler configuration conditional to guard the bench mark code. To run the bench marks use: RUSTFLAGS='--cfg=bench' cargo +nightly bench.
