Trait Implementations

impl<T> Clone for Resolver<T>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for Resolver<T>

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

Formats the value using the given formatter.

impl<T> Default for Resolver<T>

fn default() -> Resolver<T>

Returns the “default value” for a type.

impl<T: Address> Service<Connect<T>> for Resolver<T>

type Response = Connect<T>

Responses given by the service.

type Error = ConnectError

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

async fn call( &self, req: Connect<T>, _: ServiceCtx<'_, Self> ) -> Result<Connect<T>, Self::Error>

Process the request and return the response asynchronously.

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

Returns Ready when the service is able to process requests.

fn poll_shutdown(&self, cx: &mut Context<'_>) -> Poll<()>

Shutdown service.

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

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

Map this service’s output to a different type, returning a new service of the resulting type.

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

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

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

impl<T: Address, C> ServiceFactory<Connect<T>, C> for Resolver<T>

type Response = Connect<T>

Responses given by the created services.

type Error = ConnectError

Errors produced by the created services.

type Service = Resolver<T>

The kind of Service created by this factory.

type InitError = ()

Errors potentially raised while building a service.

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

Create and return a new service value asynchronously.

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

where Self: Sized,

Create and return a new service value asynchronously and wrap into 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,

Map this service’s output to a different type, returning a new service of the resulting 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,

Map this service’s error to a different error, returning 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,

Map this factory’s init error to a different error, returning a new service.
