-// Handler is a function which can turn a gemini request into a gemini response.
-//
-// A Handler MUST NOT return a nil response. Errors should be returned in the form
-// of error responses (4x, 5x, 6x response status). If the Handler should not be
-// responsible for the requested resource it can return a 51 response.
-type Handler func(context.Context, *Request) *Response
-
-// Middleware is a handle decorator.
-//
-// It returns a handler which may call the passed-in handler or not, or may
-// transform the request or response in some way.
-type Middleware func(Handler) Handler
-
-// FallthroughHandler builds a handler which tries multiple child handlers.
-//
-// The returned handler will invoke each of the passed child handlers in order,
-// stopping when it receives a response with status other than 51.

-// Filter wraps a handler with a predicate which determines whether to run the handler.
-//
-// When the predicate function returns false, the Filter returns the provided failure
-// response. The failure argument may be nil, in which case a "51 Resource does not exist."
-// response will be used.
