This crate is transcompiled from blake2b-ref

Example:

use blake2b_ref::Blake2bBuilder;

fn hash_message(msg: &[u8]) -> [u8; 32] {
    let mut output = [0u8; 32];
    let mut blake2b = Blake2bBuilder::new(32).personal(b"SMT").build();
    blake2b.update(msg);
    blake2b.finalize(&mut output);
    output
}

blake2b-ref.rs

A no_std BLAKE2B crate.

This crate is transcompiled by c2rust; the source code is from the offcial BLAKE2 ref implementation. The transcompiled source has been modified slightly to support no_std.

The API design is highly inspired - almost copy from https://github.com/nervosnetwork/blake2b-rs.
