Struct Map 

pub struct Map<F, S, Res> { /* private fields */ }

Service produced by the map combinator.

This is created by the Service::map() and ServiceChain::map() methods.

Trait Implementations

impl<F, S, Res> Clone for Map<F, S, Res>

where F: Clone, 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<F, S, Res> Debug for Map<F, S, Res>

where S: Debug,

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

Formats the value using the given formatter.

impl<F, S, St, Req, Res> Service<St, Req> for Map<F, S, Res>

where S: Service<St, Req>, F: Fn(S::Res) -> Res,

type Res = Res

Response produced by the service.

type Error = <S as Service<St, Req>>::Error

Error produced while checking readiness or processing a request.

async fn call(&self, req: Req, ctx: Ctx<'_, Self, St>) -> Result<Res, S::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.
