Module matcher

matcher utilities for any middleware where need to match on incoming requests within a given Context

This module provides the Matcher trait and convenience utilities around it.

• Examples of this are iterator “reducers” as made available via IteratorMatcherExt, as well as optional Matcher::or and Matcher::and trait methods.
• These all serve as building blocks together with And, Or, Not and a bool to combine and transform any kind of Matcher.
• And finally there is MatchFn, easily created using match_fn to create a Matcher from any compatible Fn.

Structs

• And
  A matcher that matches if all of the inner matchers match.
• ExtensionMatcher
  A matcher which allows you to match based on an extension, either by comparing with an extension (ExtensionMatcher::with_const), or using a custom predicate (ExtensionMatcher::with_fn).
• Not
  A matcher that matches if the inner matcher does not match.
• Or
  A matcher that matches if any of the inner matchers match.

Traits

• IteratorMatcherExt
  Extension to apply matcher operations to an Iterator of Matchers.
• MatchFn
  A MatchFn is a Matcher implemented using a function.
• Matcher
  A condition to decide whether Request within the given Context matches for router or other middleware purposes.

Functions

• match_fn
  Create a MatchFn from a function.
