Struct tower::make::Shared [−][src]
pub struct Shared<S> { /* fields omitted */ }
make
only.Expand description
A MakeService
that produces services by cloning an inner service.
Example
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>> { Poll::Ready(Ok(())) } 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) where 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 serve_make_service(make).await;
