Struct Filter 

pub struct Filter<St, In>(/* private fields */);

Identity request filter.

The default filter of applications, scopes, and resources. It passes requests through unchanged.

Trait Implementations

impl<St, In> Debug for Filter<St, In>

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

Formats the value using the given formatter.

impl<St: State, In> Service<St, WebRequest<In>> for Filter<St, In>

type Res = WebRequest<In>

Response produced by the service.

type Error = WebError<St, <St as State>::Error>

Error produced while checking readiness or processing a request.

async fn call( &self, req: WebRequest<In>, _: Ctx<'_, Self, St>, ) -> Result<Self::Res, Self::Error>

Processes a request and asynchronously returns the response.

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

Waits until the service is ready to process a request.

async fn shutdown(&self, ctx: Ctx<'_, Self, St>)

Shuts down the service.

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

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

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

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

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

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

fn and_then<Next, F>(self, f: F) -> ServiceChain<AndThen<Self, Next>, St, Req>

where Self: Sized, Next: Service<St, Self::Res, Error = Self::Error>, F: IntoService<Next, St, Self::Res>,

Calls another service after this service completes successfully.

fn pipeline(self, st: St) -> Pipeline<Req, Self::Res, Self::Error>

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

Wraps this service and its state in a Pipeline.

impl<St: State, In> ServiceFactory<St, WebRequest<In>> for Filter<St, In>

type Res = WebRequest<In>

Response produced by the created services.

type Error = WebError<St, <St as State>::Error>

Error produced by the created services.

type Service = Filter<St, In>

The type of Service produced by this factory.

type InitError = Failure

Error that can occur while constructing a service.

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

Asynchronously creates a service using the supplied state.

async fn pipeline( &self, st: St, ) -> Result<Pipeline<Req, Self::Res, Self::Error>, Self::InitError>

where Self: 'static, St: 'static, Req: 'static,

Creates a service and wraps it with its state in a Pipeline.

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

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

Returns a factory whose services map responses to a different type.

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

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

Returns a factory whose services map errors to a different type.

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

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 and_then<U, F>( self, f: F, ) -> ServiceChainFactory<AndThenFactory<Self, U>, St, Req>

where Self: Sized, U: ServiceFactory<St, Self::Res, Error = Self::Error, InitError = Self::InitError>, F: IntoServiceFactory<U, St, Self::Res>,

Chains another factory after this factory’s services.

fn boxed( self, ) -> BoxServiceFactory<St, Req, Self::Res, Self::Error, Self::InitError>

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

Creates a boxed service factory.
