Trait ExcService 

pub trait ExcService<R>
where
    R: Request,
{
    type Future: Future<Output = Result<<R as Request>::Response, ExchangeError>>;

    // Required methods
    fn poll_ready(
        &mut self,
        cx: &mut Context<'_>,
    ) -> Poll<Result<(), ExchangeError>>;
    fn call(&mut self, req: R) -> Self::Future;

    // Provided method
    fn as_service(&mut self) -> AsService<'_, Self, R>
       where Self: Sized { ... }
}

An alias of Service that requires the input type to be a Request, and the error type to be ExchangeError.

Basically, Request is just indicating that the input type has a fixed response type.

Required Associated Types

type Future: Future<Output = Result<<R as Request>::Response, ExchangeError>>

The future response value.

Required Methods

fn poll_ready( &mut self, cx: &mut Context<'_>, ) -> Poll<Result<(), ExchangeError>>

See Service::poll_ready for more details.

fn call(&mut self, req: R) -> Self::Future

See Service::call for more details.

Provided Methods

fn as_service(&mut self) -> AsService<'_, Self, R>

where Self: Sized,

Convert to a Service.
