Struct Callback

pub struct Callback<S, M> { /* private fields */ }

Middleware that adds callbacks to a Service.

See the module docs for an example.

Implementations

impl<S, M> Callback<S, M>

pub fn new(inner: S, make_callback_handler: M) -> Self

Create a new Callback.

pub fn layer(make_handler: M) -> CallbackLayer<M>

where M: MakeCallbackHandler,

Returns a new Layer that wraps services with a CallbackLayer middleware.

pub fn inner(&self) -> &S

Gets a reference to the underlying service.

pub fn inner_mut(&mut self) -> &mut S

Gets a mutable reference to the underlying service.

pub fn into_inner(self) -> S

Consumes self, returning the underlying service.

Trait Implementations

impl<S: Clone, M: Clone> Clone for Callback<S, M>

fn clone(&self) -> Callback<S, M>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<S: Debug, M: Debug> Debug for Callback<S, M>

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

Formats the value using the given formatter.

impl<S, M, RequestBody, ResponseBodyT> Service<Request<RequestBody>> for Callback<S, M>

where S: Service<Request<RequestBody>, Response = Response<ResponseBodyT>, Error: Display + 'static>, M: MakeCallbackHandler, RequestBody: Body<Error: Display + 'static>, ResponseBodyT: Body<Error: Display + 'static>,

type Response = Response<ResponseBody<ResponseBodyT, <M as MakeCallbackHandler>::Handler>>

Responses given by the service.

type Error = <S as Service<Request<RequestBody>>>::Error

Errors produced by the service.

type Future = ResponseFuture<<S as Service<Request<RequestBody>>>::Future, <M as MakeCallbackHandler>::Handler>

The future response value.

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

Returns Poll::Ready(Ok(())) when the service is able to process requests.

fn call(&mut self, request: Request<RequestBody>) -> Self::Future

Process the request and return the response asynchronously.
