Module hyper::service

Asynchronous Services

A 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>>.

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 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.

Traits

• HttpService
  An asynchronous function from Request to Response.
• Service
  An asynchronous function from a Request to a Response.

Functions

• service_fn
  Create a Service from a function.
