Struct memchr::arch::all::twoway::Finder

source ·
pub struct Finder(/* private fields */);
Expand description

A forward substring searcher that uses the Two-Way algorithm.

Implementations§

source§

impl Finder

source

pub fn new(needle: &[u8]) -> Finder

Create a searcher that finds occurrences of the given needle.

An empty needle results in a match at every position in a haystack, including at haystack.len().

source

pub fn find(&self, haystack: &[u8], needle: &[u8]) -> Option<usize>

Returns the first occurrence of needle in the given haystack, or None if no such occurrence could be found.

The needle given must be the same as the needle provided to Finder::new.

An empty needle results in a match at every position in a haystack, including at haystack.len().
