Struct TracingService

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

A Service implementation that automatically enters/exits tracing spans for the wrapped inner service.

Implementations

impl<S, F> TracingService<S, F>

pub fn new(inner: S, make_span: F) -> Self

Trait Implementations

impl<S: Clone, F: Clone> Clone for TracingService<S, F>

fn clone(&self) -> TracingService<S, F>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<S, F> Service for TracingService<S, F>

where S: Service, F: Fn(&S::Request) -> Option<Span>,

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 Future = Either<<S as Service>::Future, Instrumented<<S as Service>::Future>>

The future response value.

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

Returns Ready when the service is able to process requests.

fn call(&mut self, req: Self::Request) -> Self::Future

Process the request and return the response asynchronously.

fn map<F, R>(self, f: F) -> Map<Self, F, R>

where Self: Sized, F: FnMut(Self::Response) -> R,

Map this service’s output to a different type, returning a new service of the resulting type.

fn map_err<F, E>(self, f: F) -> MapErr<Self, F, E>

where Self: Sized, F: Fn(Self::Error) -> E,

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