Struct KeepAlive

pub struct KeepAlive<R, E, F> { /* private fields */ }

KeepAlive service factory

Controls min time between requests.

Implementations

impl<R, E, F> KeepAlive<R, E, F>

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

pub fn new(ka: Millis, err: F) -> Self

Construct KeepAlive service factory.

ka - keep-alive timeout err - error factory function

Trait Implementations

impl<R, E, F> Clone for KeepAlive<R, E, F>

where F: Clone,

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<R, E, F> Debug for KeepAlive<R, E, F>

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

Formats the value using the given formatter.

impl<R, E, F, C> ServiceFactory<R, C> for KeepAlive<R, E, F>

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

type Response = R

Responses given by the created services.

type Error = E

Errors produced by the created services.

type Service = KeepAliveService<R, E, F>

The kind of Service created by this factory.

type InitError = Infallible

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.
