Trait Service

pub trait Service<Request>:
    Sized
    + Send
    + Sync
    + 'static {
    type Response: Send + 'static;
    type Error: Send + Sync + 'static;

    // Required method
    fn call(
        &self,
        request: Request,
    ) -> impl Future<Output = Result<Self::Response, Self::Error>> + Send + '_;

    // Provided method
    fn boxed(self) -> BoxService<Request, Self::Response, Self::Error> { ... }
}

Required Associated Types

type Response: Send + 'static

Responses given by the service.

type Error: Send + Sync + 'static

Errors produced by the service.

Required Methods

fn call( &self, request: Request, ) -> impl Future<Output = Result<Self::Response, Self::Error>> + Send + '_

Process the request and return the response asynchronously.

Provided Methods

fn boxed(self) -> BoxService<Request, Self::Response, Self::Error>

Box this service to allow for dynamic dispatch.

Object Safety

This trait is not object safe.
