[−][src]Struct aho_corasick::Match
A representation of a match reported by an Aho-Corasick automaton.
A match has two essential pieces of information: the identifier of the pattern that matched, along with the start and end offsets of the match in the haystack.
Examples
Basic usage:
use aho_corasick::AhoCorasick; let ac = AhoCorasick::new(&[ "foo", "bar", "baz", ]); let mat = ac.find("xxx bar xxx").expect("should have a match"); assert_eq!(1, mat.pattern()); assert_eq!(4, mat.start()); assert_eq!(7, mat.end());
Methods
impl Match
[src]
pub fn pattern(&self) -> usize
[src]
Returns the identifier of the pattern that matched.
The identifier of a pattern is derived from the position in which it
was originally inserted into the corresponding automaton. The first
pattern has identifier 0
, and each subsequent pattern is 1
, 2
and so on.
pub fn start(&self) -> usize
[src]
The starting position of the match.
pub fn end(&self) -> usize
[src]
The ending position of the match.
pub fn is_empty(&self) -> bool
[src]
Returns true if and only if this match is empty. That is, when
start() == end()
.
An empty match can only be returned when the empty string was among the patterns used to build the Aho-Corasick automaton.
