Implementations

impl<T> ConcurrencyLimit<T>[−]

pub fn new(inner: T, max: usize) -> Self[−]

Create a new concurrency limiter.

pub fn get_ref(&self) -> &T[−]

Get a reference to the inner service

pub fn get_mut(&mut self) -> &mut T[−]

Get a mutable reference to the inner service

pub fn into_inner(self) -> T[−]

fn clone(&self) -> ConcurrencyLimit<S>[−]

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)[−]

Performs copy-assignment from source.

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

Formats the value using the given formatter.

impl<S> Load for ConcurrencyLimit<S> where
    S: Load, [+]

[+] Show hidden undocumented items

type Metric = S::Metric

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

fn load(&self) -> Self::Metric[−]

Obtains a service’s load.

impl<S, Request> Service<Request> for ConcurrencyLimit<S> where
    S: Service<Request>, [+]

[+] Show hidden undocumented items

type Response = S::Response

Responses given by the service.

type Error = S::Error

Errors produced by the service.

type Future = ResponseFuture<S::Future>

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, request: Request) -> Self::Future[−]

Process the request and return the response asynchronously.
