• AndThen

• Around
  Wraps around the remaining handler or middleware chain.
• Before
  Maps the input before the handler calls.
• BoxHandler
  A Clone + Send boxed Handler.
• CatchError
  Catches rejected error while calling the handler.
• CatchUnwind
  Catches unwinding panics while calling the handler.
• FnExtHandler
  A wrapper of the extractors handler.
• Map
  Maps the Ok value of the output if after the handler called.
• MapErr
  Maps the Err value of the output if after the handler called.
• MapInToResponse

• OrElse
  Calls op if the output is Err, otherwise returns the Ok value of the output.
• ServiceHandler

  Combines two different handlers having the same associated types into a single type.

Traits

• FnExt
  A handler with extractors.
• 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.
