Function EverCrypt_Hash_Incremental_update

pub unsafe extern "C" fn EverCrypt_Hash_Incremental_update(
    s: *mut EverCrypt_Hash_Incremental_hash_state,
    data: *mut u8,
    len: u32,
) -> EverCrypt_Error_error_code

Feed an arbitrary amount of data into the hash. This function returns EverCrypt_Error_Success for success, or EverCrypt_Error_MaximumLengthExceeded if the combined length of all of the data passed to update (since the last call to init) exceeds 2^61-1 bytes or 2^64-1 bytes, depending on the choice of algorithm. Both limits are unlikely to be attained in practice.
