Struct PendingRequests

pub struct PendingRequests<S, I = NoInstrument> { /* private fields */ }

Expresses load based on the number of currently-pending requests.

Trait Implementations

impl<S: Debug, I: Debug> Debug for PendingRequests<S, I>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<S, I> Load for PendingRequests<S, I>

type Metric = Count

A comparable load metric. Lesser values are “preferable” to greater values.

fn load(&self) -> Count

Obtains a service’s load.

impl<S, I, Request> Service<Request> for PendingRequests<S, I>

where S: Service<Request>, I: Instrument<Handle, S::Response>,

type Response = <I as Instrument<Handle, <S as Service<Request>>::Response>>::Output

Responses given by the service.

type Error = <S as Service<Request>>::Error

Errors produced by the service.

type Future = InstrumentFuture<<S as Service<Request>>::Future, I, Handle>

The future response value.

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

Returns Poll::Ready(Ok(())) when the service is able to process requests.

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

Process the request and return the response asynchronously.
