The hash engine types have a `length` field that is used to cache the number of bytes hashed so far, as such it is an arbitrary number and could use a `u64` instead of `usize`. While we are at it rename `length` to `bytes_hashed` to remove any ambiguity of what this field is. Note this field is private, we already have the public getter `n_bytes_hashes` to get the value. Introduce a private function `incomplete_block_size`, the purpose of this function is to put all the casts in one place so they can be well documented and easily understood. Fix: #3016 |

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 ancillary thing, it exposes hexadecimal serialization and deserialization, since these are needed to display hashes anway.
Minimum Supported Rust Version (MSRV)
This library should always compile with any combination of features on Rust 1.63.0.
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
.
