Struct WebMiddleware 

pub struct WebMiddleware<S, St> { /* private fields */ }

Service produced by WebStack layers.

Wraps a middleware service and converts its errors into WebError.

Trait Implementations

impl<S, St> Clone for WebMiddleware<S, St>

where S: Clone,

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<S: Debug, St: Debug> Debug for WebMiddleware<S, St>

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

Formats the value using the given formatter.

impl<S, St, In> Service<St, WebRequest<In>> for WebMiddleware<S, St>

where S: Service<St, WebRequest<In>, Res = WebResponse>, S::Error: WebResponseError<St, St::Error>, St: State,

type Res = WebResponse

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: 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.
