}

Single-substring searcher based on Avx2Searcher but with dynamic algorithm selection.

It has specialized cases for zero-length needles, which are found in all haystacks, and one-length needles, which uses MemchrSearcher. For needles up to a length of thirteen it uses specialized versions of Avx2Searcher, finally falling back to the generic version of Avx2Searcher for longer needles.

Implementations

impl DynamicAvx2Searcher[src]

pub unsafe fn new(needle: Box<[u8]>) -> Self[src]

This is supported with target feature avx2 only.

Creates a new searcher for needle. By default, position is set to the last character in the needle.

pub unsafe fn with_position(needle: Box<[u8]>, position: usize) -> Self[src]

This is supported with target feature avx2 only.

Same as new but allows additionally specifying the position to use.

pub unsafe fn inlined_search_in(&self, haystack: &[u8]) -> bool[src]

This is supported with target feature avx2 only.

Inlined version of search_in for hot call sites.

pub unsafe fn search_in(&self, haystack: &[u8]) -> bool[src]

This is supported with target feature avx2 only.

Performs a substring search for the needle within haystack.
