Struct FnService 

pub struct FnService<F, Req, Res, Err> { /* private fields */ }

Service implementation for an AsyncFn(Req) -> Result<Res, Err> fn.

Trait Implementations

impl<F, Req, Res, Err> Clone for FnService<F, Req, Res, Err>

where F: 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, Req, Res, Err> Debug for FnService<F, Req, Res, Err>

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

Formats the value using the given formatter.

impl<F, St, Req, Res, Err> IntoService<FnService<F, Req, Res, Err>, St, Req> for F

where F: AsyncFn(Req) -> Result<Res, Err>,

fn into_service(self) -> FnService<F, Req, Res, Err>

Convert to a Service

impl<F, St, Req, Res, Err> Service<St, Req> for FnService<F, Req, Res, Err>

where F: AsyncFn(Req) -> Result<Res, Err>,

type Res = Res

Responses that the service could provide.

type Error = Err

Errors produced by the service while checking readiness or executing a call.

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

Processes a request and asynchronously returns the response.

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

Returns when the service is ready to process requests.

async fn shutdown(&self, cfg: 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>,

Call another service after call to this one has resolved successfully.

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

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

Wraps it in a container.
