• BoxHandler
  A Clone + Send boxed Handler.
• CatchError
  Catches rejected error while calling the handler.

• OrElse

• Handler
  A simplified asynchronous interface for handling input and output.
• HandlerExt
  The HandlerExt trait, which provides adapters for chaining and composing handlers.
• IntoHandler
  The trait implemented by types that can be converted to a Handler.
• Transform
  Then Transform trait defines the interface of a handler factory that wraps inner handler to a Handler during construction.

Type Aliases

• Next
  Represents a middleware parameter, which is a tuple that includes Requset and BoxHandler.
