ctutils: core::num::NonZero<T> support#1368
Merged
Conversation
Adds initial support for the following aliases of `NonZero<T>`: - NonZeroI8 - NonZeroI16 - NonZeroI32 - NonZeroI64 - NonZeroI128 - NonZeroU8 - NonZeroU16 - NonZeroU32 - NonZeroU64 - NonZeroU128 (We can't yet implement things generically because `NonZero` bounds on `T: ZeroablePrimitive` which is unstable) The following traits are impl'd for all of the above: - `CtAssign` - `CtEq` - `CtNeg` - `CtSelect` The following are impl'd for the unsigned `NonZeroU*` types: - `CtGt` - `CtLt`

## Added - `core::num::NonZero<T>` support (#1368) - Pluggable trait impls for `[T]` and `[T; N]` with helper traits: (#1388) - `CtAssign`: `CtAssignSlice` - `CtEq`: `CtEqSlice` - `CtSelect`: `CtSelectArray` - `CtSelectUsingCtAssign` marker trait (#1391) ## Changed - Split `CtAssign` out of `CtSelect` (#1363) - Bump `cmov` to v0.5 (#1386) ## Removed - `BytesCtEq`/`BytesCtSelect` no longer needed because default `[u8]` impls are fast (#1376) - `target_pointer_width` gating (#1389) - `unsafe` code (#1405)
