Struct SetMatches 

pub struct SetMatches { /* private fields */ }

Which patterns of a RegexSet matched one text.

Stored as the matching indices rather than as a bit per pattern, because that is what the engine reports and because the interesting case is a large set with a few hits. SetMatches::matched therefore costs a binary search rather than an array index — nothing a caller will measure, and it makes SetMatches::iter free.

Implementations

impl SetMatches

pub fn matched_any(&self) -> bool

Whether any pattern matched.

pub fn matched(&self, index: usize) -> bool

Whether the pattern at index matched. false for an index past the end of the set, which cannot have matched anything.

pub fn len(&self) -> usize

How many patterns the set holds — not how many matched. This is regex’s meaning for the same name; SetMatches::iter counts the hits.

pub fn is_empty(&self) -> bool

Whether the set that produced this held no patterns at all.

pub fn iter( &self, ) -> impl ExactSizeIterator<Item = usize> + DoubleEndedIterator + '_

The indices of the patterns that matched, ascending.
