Struct SubstringSetMatcher

pub struct SubstringSetMatcher<'a> { /* private fields */ }

This matcher is a variation on [SubstringMatcher] that searches for a match of any of multiple substrings in the input buffer.

This is much more efficient than performing multiple independent searches with [SubstringMatcher], so should be used whenever multiple substring patterns could be matched at the same time.

Implementations

impl<'a> SubstringSetMatcher<'a>

pub fn new( patterns: Vec<Span<Cow<'a, str>>>, config: &Config, ) -> DiagResult<Self>

Create a new matcher for the given set of substring patterns

NOTE: This function will panic if the set is empty.

pub fn search<'input, 'patterns>( &'patterns self, input: Input<'input>, ) -> DiagResult<SubstringSetSearcher<'a, 'patterns, 'input>>

pub fn pattern_len(&self) -> usize

pub fn first_pattern(&self) -> Span<usize>

pub fn first_pattern_span(&self) -> SourceSpan

pub fn build() -> SubstringSetBuilder<'a>

Get a builder for configuring and building a new SubstringSetMatcher

pub fn try_match_all<'input>( &self, input: Input<'input>, ) -> Vec<MatchInfo<'input>>

Search for all of the non-overlapping matches in the input

pub fn try_match_overlapping<'input>( &self, input: Input<'input>, ) -> Vec<MatchInfo<'input>>

Search for all of the matches in the input, including overlapping matches
