| //! |
| //! A [`Service`](Service) is a trait representing an asynchronous |
| //! function of a request to a response. It's similar to |
| //! `async fn(Request) -> Result<Response, Error>`. |
| //! |
| //! The argument and return value isn't strictly required to be for HTTP. |
| //! Therefore, hyper uses several "trait aliases" to reduce clutter around |
| //! bounds. These are: |
| //! |
| //! - `HttpService`: This is blanketly implemented for all types that |
| //! implement `Service<http::Request<B1>, Response = http::Response<B2>>`. |
| //! - `MakeService`: When a `Service` returns a new `Service` as its "response", |
| //! we consider it a `MakeService`. Again, blanketly implemented in those cases. |
| //! - `MakeConnection`: A `Service` that returns a "connection", a type that |
| //! implements `AsyncRead` and `AsyncWrite`. |
| //! |
| //! # HttpService |
| //! |
| //! In hyper, especially in the server setting, a `Service` is usually bound |
| //! to a single connection. It defines how to respond to **all** requests that |
| //! connection will receive. |
| //! |
| //! The helper [`service_fn`](service_fn) should be sufficient for most cases, but |
| //! if you need to implement `Service` for a type manually, you can follow the example |
| //! in `service_struct_impl.rs`. |
| //! |
| //! # MakeService |
| //! |
| //! Since a `Service` is bound to a single connection, a [`Server`](crate::Server) |
| //! needs a way to make them as it accepts connections. This is what a |
| //! `MakeService` does. |
| //! |
| //! Resources that need to be shared by all `Service`s can be put into a |
| //! `MakeService`, and then passed to individual `Service`s when `call` |
| //! is called. |
