Struct FnMiddleware 

pub struct FnMiddleware<F, S, St, Req, In, Out, Err> { /* private fields */ }

Middleware backed by an asynchronous function.

Trait Implementations

impl<F, S, St, Req, In, Out, Err> Clone for FnMiddleware<F, S, St, Req, In, Out, 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, S, St, Req, In, Out, Err> Debug for FnMiddleware<F, S, St, Req, In, Out, Err>

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

Formats the value using the given formatter.

impl<F, S, St, Req, In, Out, Err> Middleware<S, St> for FnMiddleware<F, S, St, Req, In, Out, Err>

where S: Service<St, Req>, F: AsyncFn(In, &ApplyCtx<'_, S, St, Req>) -> Result<Out, Err> + Clone, Err: From<S::Error>,

type Service = Apply<S, St, Req, F, In, Out, Err>

Service created by this middleware.

fn create(&self, _: &St, service: S) -> Self::Service

Creates and returns a new middleware service.

fn apply_to<Sf, Req>( self, factory: Sf, ) -> ServiceChainFactory<ApplyMiddleware<Self, Sf>, St, Req>

where Sf: ServiceFactory<St, Req, Service = S>, Self: Sized, Self::Service: Service<St, Req>,

Creates a service factory that instantiates a service and applies the current middleware to it.
