Description

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):

contains_bytes
find_bytes
rfind_bytes
split_bytes
rsplit_bytes
split_bytes_once
rsplit_bytes
splitn_bytes
rsplitn_bytes
replace_bytes
replacen_bytes
starts_with_bytes
ends_with_bytes
matches_bytes
rmatches_bytes
match_indices_bytes
rmatch_indices_bytes
trim_bytes_start_matches
trim_bytes_end_matches
strip_bytes_prefix
strip_bytes_suffix
