Jack O'Connor efbfa0463c integrate assembly implementations into the blake3 crate 2020-02-12 10:23:17 -05:00
Jack O'Connor fc219f4f8d Hasher::update_with_join 
This is a new interface that allows the caller to provide a
multi-threading implementation. It's defined in terms of a new `Join`
trait, for which we provide two implementations, `SerialJoin` and
`RayonJoin`. This lets the caller control when multi-threading is used,
rather than the previous all-or-nothing design of the "rayon" feature.

Although existing callers should keep working, this is a compatibility
break, because callers who were relying on automatic multi-threading
before will now be single-threaded. Thus the next release of this crate
will need to be version 0.2.

See https://github.com/BLAKE3-team/BLAKE3/issues/25 and
https://github.com/BLAKE3-team/BLAKE3/issues/54.

Jack O'Connor 52ea6487f8 switch to representing CVs as words for the compression function 
The portable implementation was getting slowed down by converting back
and forth between words and bytes.

I made the corresponding change on the C side first
(12a37be8b5),
and as part of this commit I'm re-vendoring the C code. I'm also
exposing a small FFI interface to C so that blake3_neon.c can link
against portable.rs rather than blake3_portable.c, see c_neon.rs.
