| //! |
| //! For both [Clients](crate::client) and [Servers](crate::server), requests and |
| //! responses use streaming bodies, instead of complete buffering. This |
| //! allows applications to not use memory they don't need, and allows exerting |
| //! back-pressure on connections by only reading when asked. |
| //! |
| //! There are two pieces to this in hyper: |
| //! |
| //! - **The [`HttpBody`](HttpBody) trait** describes all possible bodies. |
| //! hyper allows any body type that implements `HttpBody`, allowing |
| //! applications to have fine-grained control over their streaming. |
| //! - **The [`Body`](Body) concrete type**, which is an implementation of |
| //! `HttpBody`, and returned by hyper as a "receive stream" (so, for server |
| //! requests and client responses). It is also a decent default implementation |
| //! if you don't have very custom needs of your send streams. |
