Trait ServiceRef 

pub trait ServiceRef<IO>: Sealed<IO> {
    type Future: Future<Output = Result<Self::Response, Self::Error>>;
    type Response;
    type Error;

    // Required methods
    fn poll_ready(
        &mut self,
        cx: &mut Context<'_>,
    ) -> Poll<Result<(), Self::Error>>;
    fn call(&mut self, stream: &IO) -> Self::Future;
}

A tower::Service which takes a reference to a conenction type, usually in a “make service” context. Effectively this is Service<&IO>, but gets around the limitations of an impl with lifetimes.

Required Associated Types

type Future: Future<Output = Result<Self::Response, Self::Error>>

The future returned by the service.

type Response

The response type of the service.

type Error

The error type of the service.

Required Methods

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

Poll the service to determine if it is ready to process requests.

fn call(&mut self, stream: &IO) -> Self::Future

Call the service with a reference to the connection.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementors

impl<IO, T, F, R, E> ServiceRef<IO> for T

where T: for<'a> Service<&'a IO, Future = F, Response = R, Error = E>, F: Future<Output = Result<R, E>>,

type Future = F

type Response = R

type Error = E
