Trait Client

    type Response;
    type Future: Future<Output = Result<Self::Response>> + 'a;

    // Required method
    fn call(&'a mut self, ctx: Context, request: Req) -> Self::Future;

    // Provided methods
    fn map_response<F, R>(self, f: F) -> MapResponse<Self, F>

       where F: FnMut(Req2) -> Req,

}

Sends multiplexed requests to, and receives responses from, a server.

Required Associated Types

type Response

The response type.

type Future: Future<Output = Result<Self::Response>> + 'a

The future response.

Required Methods

fn call(&'a mut self, ctx: Context, request: Req) -> Self::Future

Initiates a request, sending it to the dispatch task.

Returns a Future that resolves to this client and the future response once the request is successfully enqueued.

Provided Methods

fn map_response<F, R>(self, f: F) -> MapResponse<Self, F>

where F: FnMut(Self::Response) -> R, Self: Sized,

Returns a Client that applies a post-processing function to the returned response.

fn with_request<F, Req2>(self, f: F) -> WithRequest<Self, F>

where F: FnMut(Req2) -> Req, Self: Sized,

Returns a Client that applies a pre-processing function to the request.
