fastchr-0.3.0 doesn't have any documentation.
This crate provides one function: `fastchr`, which very quickly finds the first occurrence of a given byte in a slice.
`fastchr` is implemented using SIMD intrinsics and runtime CPU feature detection so it will always use the fastest method available
on a platform. If SIMD features are not available, `fastchr` falls back to using `memchr`.
