Package middleware provides several standard middleware implementations.

New creates a new Mux without any routes or middleware.

The key used to communicate to the NotFound handler what methods would have been allowed if they'd been provided.

C is a per-request context object which is threaded through all compliant middleware layers and to the final request handler.

Mux is an HTTP multiplexer, much like net/http's ServeMux.

Handler is a superset of net/http's http.Handler, which also includes a mechanism for serving requests with a context.

A Pattern determines whether or not a given request matches some criteria.

HandlerFunc is like net/http's http.HandlerFunc, but supports a context object.
