//! Types and traits to build and send responses.
//!
//! The return type of a Rocket handler can be any type that implements the
//! [`Responder`](::response::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
//! `Responder`s `A`, `B`, and `C`. This is normal and encouraged as the type
//! names typically illustrate the intended response.
//!
//! # Contrib
//!
//! The [`contrib` crate](rocket_contrib) contains several useful `Responder`s
//! including [`Template`](rocket_contrib::Template) and
//! [`Json`](rocket_contrib::Json).
