Struct Batch 

pub struct Batch<T, Request>
where
    T: Service<BatchControl<Request>>,
{ /* private fields */ }

Allows batch processing of requests.

See the module documentation for more details.

Implementations

impl<T, Request> Batch<T, Request>

where T: Service<BatchControl<Request>>, T::Error: Into<BoxError>,

pub fn new(service: T, size: usize, time: Duration) -> Self

where T: Send + 'static, T::Future: Send, T::Error: Send + Sync, Request: Send + 'static,

Creates a new Batch wrapping service.

The wrapper is responsible for telling the inner service when to flush a batch of requests.

The default Tokio executor is used to run the given service, which means that this method must be called while on the Tokio runtime.

pub fn pair( service: T, size: usize, time: Duration, ) -> (Self, Worker<T, Request>)

where T: Send + 'static, T::Future: Send, T::Error: Send + Sync, Request: Send + 'static,

Creates a new Batch wrapping service, but returns the background worker.

This is useful if you do not want to spawn directly onto the tokio runtime but instead want to use your own executor. This will return the Batch and the background Worker that you can then spawn.

Trait Implementations

impl<T, Request> Clone for Batch<T, Request>

where T: Service<BatchControl<Request>>,

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T, Request: Debug> Debug for Batch<T, Request>

where T: Service<BatchControl<Request>> + Debug, T::Future: Debug,

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

Formats the value using the given formatter.

impl<T, Request> Service<Request> for Batch<T, Request>

where T: Service<BatchControl<Request>>, T::Error: Into<BoxError>,

type Response = <T as Service<BatchControl<Request>>>::Response

Responses given by the service.

type Error = Box<dyn Error + Send + Sync>

Errors produced by the service.

type Future = ResponseFuture<<T as Service<BatchControl<Request>>>::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.
