`keccak` was previously excluded from the toplevel workspace due to its
MSRV of 1.41 and incompatibilities with packages used by `ascon`.
This bumps the edition, changes the version to `0.2.0-pre` to denote it
contains breaking changes (though this is not intended to be a
`0.2.0-pre` release), and bumps MSRV.
With the MSRV bumped, `keccak` can and has been re-added to the toplevel
workspace.
Due to the generics approach of the keccak_p routine, the performance
degrades significantly. To encounter this the commonly used functions
are now defined by macros.
The build is failing because `keccak` has a very old MSRV of 1.41, which
after merging #40 (which bumped the `ascon` edition to 2021) broke the
build because it can't handle the `edition` key.
As a workaround, this excludes `keccak` from the toplevel workspace so
it doesn't try to read the `ascon` edition key.
Separately, we should probably bump the `keccak` edition to 2021 as well
and release `keccak` v0.2.0, but that is left for future work.
- Bumps the crate's edition to 2018, which is MSRV-compatible.
- Adds a more expansive set of lints
- Adds the `missing_docs` lint, and adds docs where missing
- Fixes tests on ARMv8
Gates `asm` support under a crate feature.
Uses the `cpufeatures` crate to detect the presence of the `sha3`
extension for ARMv8 CPUs, automatically falling back to a software
implementation if it isn't available.
When the `asm` feature is enabled on `aarch64` targets, exposes
`f1600_asm` that relies on ARMv8 `sha3` hardware intrinsics.
