Struct TracingTransform

pub struct TracingTransform<S, U, F> { /* private fields */ }

A Transform implementation that wraps services with a TracingService.

Implementations

impl<S, U, F> TracingTransform<S, U, F>

pub fn new(make_span: F) -> Self

Trait Implementations

impl<S, U, F> Transform<S> for TracingTransform<S, U, F>

where S: Service, U: ServiceFactory<Request = S::Request, Response = S::Response, Error = S::Error, Service = S>, F: Fn(&S::Request) -> Option<Span> + Clone,

type Request = <S as Service>::Request

Requests handled by the service.

type Response = <S as Service>::Response

Responses given by the service.

type Error = <S as Service>::Error

Errors produced by the service.

type Transform = TracingService<S, F>

The TransformService value created by this factory

type InitError = <U as ServiceFactory>::InitError

Errors produced while building a transform service.

type Future = Ready<Result<<TracingTransform<S, U, F> as Transform<S>>::Transform, <TracingTransform<S, U, F> as Transform<S>>::InitError>>

The future response value.

fn new_transform(&self, service: S) -> Self::Future

Creates and returns a new Transform component, asynchronously

fn map_init_err<F, E>(self, f: F) -> TransformMapInitErr<Self, S, F, E>

where Self: Sized, F: Fn(Self::InitError) -> E + Clone,

Map this transforms’s factory error to a different error, returning a new transform service factory.
