#func ⇒ Object (readonly)

Fancy predicates for HTTP requests. Features:

  • and/or/not combinators

  • If a predicate raises an error, it is caught and treated as falsey. simplifies predicates. For example: headers.starts_with?(‘application/’) will raise if no Allow header was sent, however we really just want to treat that as a non-match.

  • Parameter extraction. A matcher can return an augmented Request as the truthy value.
