Enum Control 

pub enum Control<E> {
    WrBackpressure(WrBackpressure),
    Stop(Reason<E>),
}

Connection control messages

Variants

WrBackpressure(WrBackpressure)

Write back-pressure is enabled/disabled

Stop(Reason<E>)

Dispatcher is preparing for shutdown.

The control service will receive this message only once. After receiving this message dispatcher stops.

Trait Implementations

impl<E: Debug> Debug for Control<E>

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

Formats the value using the given formatter.

impl<S, E, R> Service<Control<E>> for DefaultControlService<S, E, R, ()>

type Response = Option<R>

Responses given by the service.

type Error = E

Errors produced by the service when polling readiness or executing call.

async fn call( &self, _: Control<E>, _: ServiceCtx<'_, Self>, ) -> Result<Self::Response, Self::Error>

Processes a request and returns the response asynchronously.

async fn ready(&self, ctx: ServiceCtx<'_, Self>) -> Result<(), Self::Error>

Returns when the service is ready to process requests.

async fn shutdown(&self)

Shuts down the service.

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

Polls the service from the current async task.

fn map<F, Res>(self, f: F) -> ServiceChain<Map<Self, F, Req, Res>, Req>

where Self: Sized, F: Fn(Self::Response) -> Res,

Maps this service’s output to a different type, returning a new service.

fn map_err<F, E>(self, f: F) -> ServiceChain<MapErr<Self, F, E>, Req>

where Self: Sized, F: Fn(Self::Error) -> E,

Maps this service’s error to a different type, returning a new service.

impl<S, E, R, Err> ServiceFactory<Control<E>, S> for DefaultControlService<S, E, R, Err>

type Response = Option<R>

Responses given by the created services.

type Error = E

Errors produced by the created services.

type InitError = Err

Possible errors encountered during service construction.

type Service = DefaultControlService<S, E, R>

The type of Service produced by this factory.

async fn create(&self, _: S) -> Result<Self::Service, Self::InitError>

Creates a new service asynchronously and returns it.

async fn pipeline( &self, cfg: Cfg, ) -> Result<Pipeline<Self::Service>, Self::InitError>

where Self: Sized,

Asynchronously creates a new service and wraps it in a container.

fn map<F, Res>( self, f: F, ) -> ServiceChainFactory<MapFactory<Self, F, Req, Res, Cfg>, Req, Cfg>

where Self: Sized, F: Fn(Self::Response) -> Res + Clone,

Returns a new service that maps this service’s output to a different type.

fn map_err<F, E>( self, f: F, ) -> ServiceChainFactory<MapErrFactory<Self, Req, Cfg, F, E>, Req, Cfg>

where Self: Sized, F: Fn(Self::Error) -> E + Clone,

Transforms this service’s error into another error, producing a new service.

fn map_init_err<F, E>( self, f: F, ) -> ServiceChainFactory<MapInitErr<Self, Req, Cfg, F, E>, Req, Cfg>

where Self: Sized, F: Fn(Self::InitError) -> E + Clone,

Maps this factory’s initialization error to a different error, returning a new service factory.

fn boxed( self, ) -> BoxServiceFactory<Cfg, Req, Self::Response, Self::Error, Self::InitError>

where Cfg: 'static, Req: 'static, Self: Sized + 'static,

Creates a boxed service factory.
