Defines an abstract ResponderExt trait usually implemented using the impl_responder_ext!() macro.

Required Associated Types

type Response

Required Associated Constants

const REQUEST_NAME: &'static str

Required Methods

fn send(self, response: Self::Response) -> Result<(), Error>

Provided Methods

fn unpack_fields_or_else_send<T, F>( self, fields: T, f: F, ) -> Result<(T::Unpacked, Self), Error>

where T: TryUnpack<Error = Error>, F: FnOnce() -> Self::Response, Self: Sized,

Returns an success value containing all unpacked fields and the responder, or an error value if any of the values in fields is missing.

The last argument is a closure which will compute a Self::Response. If any field is missing a value, then this function will return an error and send the computed Self::Response.

Example Usage:

  enum Error {
      UnableToStart,
  }
  let ((status, id), responder) = responder.unpack_fields_or_else_send(
      (payload.status.with_name("status"), payload.id.with_name("id")),
      |e| (e.context(format_err!("Unable to start.")), Error::UnableToStart),
  )?;

fn unpack_fields_or_respond<T>( self, fields: T, ) -> Result<(T::Unpacked, Self), Error>

where T: TryUnpack<Error = Error>, Self: ResponderExt<Response = ()> + Sized,
