pub struct FinderRev(/* private fields */);
Expand description
A reverse substring searcher that uses the Two-Way algorithm.
Implementations§
source§impl FinderRev
impl FinderRev
sourcepub fn new(needle: &[u8]) -> FinderRev
pub fn new(needle: &[u8]) -> FinderRev
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()
.
sourcepub fn rfind(&self, haystack: &[u8], needle: &[u8]) -> Option<usize>
pub fn rfind(&self, haystack: &[u8], needle: &[u8]) -> Option<usize>
Returns the last 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
FinderRev::new
.
An empty needle
results in a match at every position in a haystack,
including at haystack.len()
.
