Stats-counting RPC middleware

Implementations

source

impl<T: ActivityNotifier> Middleware<T>

source

pub fn new(stats: Arc<RpcStats>, notifier: T) -> Self

Create new Middleware with stats counter and activity notifier.

Trait Implementations

source

impl<M: Metadata, T: ActivityNotifier> Middleware<M> for Middleware<T>

type Future = FutureResponse

A returned request future.

type CallFuture = NoopCallFuture

A returned call future.

source

fn on_request<F, X>(
 &self,
 request: Request,
 meta: M,
 process: F
) -> Either<Self::Future, X> where
 F: FnOnce(Request, M) -> 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. Read more

source

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. Read more
