+//! Asynchronous Services
+//!
+//! 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.
