Struct Cache 

pub struct Cache<M, Dst, Ev>
where
    M: Service<Dst>,
{ /* private fields */ }

Available on crate feature client and crate feature client-pool and docsrs only.

A cache pool of services from the inner make service.

Created with builder().

Unnameable

This type is normally unnameable, forbidding naming of the type within code. The type is exposed in the documentation to show which methods can be publicly called.

Implementations

impl<M, Dst, Ev> Cache<M, Dst, Ev>

where M: Service<Dst>,

pub fn retain<F>(&mut self, predicate: F)

where F: FnMut(&mut M::Response) -> bool,

Retain all cached services indicated by the predicate.

pub fn is_empty(&self) -> bool

Check whether this cache has no cached services.

Trait Implementations

impl<M, Dst, Ev> Clone for Cache<M, Dst, Ev>

where M: Service<Dst> + Clone, Ev: Clone,

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<M, Dst: Debug, Ev: Debug> Debug for Cache<M, Dst, Ev>

where M: Service<Dst> + Debug, M::Response: Debug,

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

Formats the value using the given formatter.

impl<M, Dst, Ev> Service<Dst> for Cache<M, Dst, Ev>

where M: Service<Dst>, M::Future: Unpin, M::Response: Unpin, Ev: Events<BackgroundConnect<M::Future, M::Response>> + Clone + Unpin,

type Response = Cached<<M as Service<Dst>>::Response>

Responses given by the service.

type Error = <M as Service<Dst>>::Error

Errors produced by the service.

type Future = CacheFuture<M, Dst, Ev>

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, target: Dst) -> Self::Future

Process the request and return the response asynchronously.
