Module matcher 

Matcher utilities for any middleware where need to match on incoming inputs.

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).

MatcherRouter

Wrapper type that can be used to turn a tuple of (Matcher, Service) tuples into a single Service.

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 Input matches for router or other middleware purposes.

Functions

match_fn

Create a MatchFn from a function.
