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

Implementations

impl Finder

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().

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().
