Struct tower::make::Shared[][src]

pub struct Shared<S> { /* fields omitted */ }
This is supported on crate feature make only.

A MakeService that produces services by cloning an inner service.


use tower::make::{MakeService, Shared};
use tower::buffer::Buffer;
use tower::Service;
use futures::future::{Ready, ready};

// An example connection type
struct Connection {}

// An example request type
struct Request {}

// An example response type
struct Response {}

// Some service that doesn't implement `Clone`
struct MyService;

impl Service<Request> for MyService {
    type Response = Response;
    type Error = Infallible;
    type Future = Ready<Result<Response, Infallible>>;

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

    fn call(&mut self, req: Request) -> Self::Future {
        ready(Ok(Response {}))

// Example function that runs a service by accepting new connections and using
// `Make` to create new services that might be bound to the connection.
// This is similar to what you might find in hyper.
async fn serve_make_service<Make>(make: Make)
    Make: MakeService<Connection, Request>
    // ...

// Our service
let svc = MyService;

// Make it `Clone` by putting a channel in front
let buffered = Buffer::new(svc, 1024);

// Convert it into a `MakeService`
let make = Shared::new(buffered);

// Run the service and just ignore the `Connection`s as `MyService` doesn't need them
