Module matcher

I define generic traits and default implementations for matchers, objects that can be used to match zero, one or several terms.

For a list of matcher implementations, check TermMarcher’s and GraphNameMatcher’s implementors lists.

For methods using matchers (with examples), see for example Triple::matched_by, Graph::triples_matching, MutableGraph::remove_matching, MutableGraph::retain_matching, Dataset::quads_matching, MutableDataset::remove_matching, MutableDataset::retain_matching.

Structs

• Any
  A universal matcher: it matches any Term or GraphName (even the default graph).
• DatatypeMatcher
  A TermMatcher that matches all literals with a given datatype
• LanguageTagMatcher
  A TermMatcher that matches all literals with a given language tag.
• MatcherRef
  Result type of TermMatcher::matcher_ref and GraphNameMatcher::matcher_ref.
• TermMatcherGn
  Wrapper type returned by TermMatcher::gn

Traits

• GraphNameMatcher
  Generic trait for matching GraphNames.
• TermMatcher
  Generic trait for matching Terms.
