Module rocket::response

Expand description

Types and traits to build and send responses.

The return type of a Rocket handler can be any type that implements the Responder trait, which means that the type knows how to generate a Response. Among other things, this module contains several such types.

Composing

Many of the built-in Responder types chain responses: they take in another Responder and add, remove, or change information in the response. In other words, many Responder types are built to compose well. As a result, you’ll often have types of the form A<B<C>> consisting of three Responders A, B, and C. This is normal and encouraged as the type names typically illustrate the intended response.

Modules

  • content
    Contains types that set the Content-Type of a response.
  • status
    Contains types that set the status code and corresponding headers of a response.
  • stream
    Potentially infinite async Stream response types.

Structs

  • Body
    The body of a Response.
  • Builder
    Builder for the Response type.
  • Debug
    Debug prints the internal value before forwarding to the 500 error catcher.
  • Flash
