Function scratchstack_wrapper_aws_c_cal::aws_hash_finalize

pub unsafe extern "C" fn aws_hash_finalize(
    hash: *mut aws_hash,
    output: *mut aws_byte_buf,
    truncate_to: usize
) -> c_int

Completes the hash computation and writes the final digest to output. Allocation of output is the caller’s responsibility. If you specify truncate_to to something other than 0, the output will be truncated to that number of bytes. For example, if you want a SHA256 digest as the first 16 bytes, set truncate_to to 16. If you want the full digest size, just set this to 0.
