Fast substring search for strings and byte strings, using the two-way algorithm.
This is the same code as is included in Rust's libstd that powers
str::find(&str), but here it is exposed with some improvements:
- Available for byte string searches using
- Having an optional SSE4.2 accelerated version (if detected at runtime) which is even faster. Runtime detection requires the default std feature.
memchrfor the single byte case, which is ultra fast.
