type Future = Either<FutureRpcResult<M::Future, M::CallFuture>, FutureResponse>

A returned request future.

type CallFuture = NoopCallFuture

A returned call future.

fn on_request<F, X>(
    &self,
    request: Request,
    meta: Metadata,
    process: F
) -> Either<Self::Future, X> where
    F: FnOnce(Request, Metadata) -> X,
    X: Future<Item = Option<Response>, Error = ()> + Send + 'static, 

Method invoked on each request. Allows you to either respond directly (without executing RPC call) or do any additional work before and/or after processing the request.

fn on_call<F, X>(
    &self,
    call: Call,
    meta: M,
    next: F
) -> Either<Self::CallFuture, X> where
    F: Fn(Call, M) -> X + Send + Sync,
    X: 'static + Future<Item = Option<Output>, Error = ()> + Send, 

Method invoked on each call inside a request.
