Source 
pub fn hash_bytes_to_buf(
    algo: HashAlgorithm,
    data: &[u8],
    out: &mut [u8],
) -> usize
Expand description

Hash data and write hex result directly into an output buffer. Returns the number of hex bytes written. Avoids String allocation on the critical single-file fast path. out must be at least 128 bytes for BLAKE2b (64 * 2), 64 for SHA256, 32 for MD5.
