Feature gate: #![feature(byte_search)]
acp: rust-lang/libs-team#499
This is a tracking issue for byte searching: searching for a particular pattern of bytes in a &[u8], and potentially trimming, splitting or otherwise processing the input based on the matches of the pattern.
Public API
The API mirrors the one for strings at std::str::pattern::Pattern.
pub trait BytePattern: Sized {
/// Associated searcher for this pattern
type Searcher<'a>: Searcher<'a>;
// etc.
}and then adds a number of inherent methods for &[u8]. The exact set has not yet been decided, but will likely include (modulo slight naming changes):
