Example

With Tower Services

use tower::{Service, ServiceExt};
use http::{Request, Response, StatusCode};
use http_body_util::Full;
use bytes::Bytes;
use http_cache_quickcache::QuickManager;
use std::convert::Infallible;

// Example Tower service that uses QuickManager for caching
#[derive(Clone)]
struct CachingService {
    cache_manager: QuickManager,
}

impl Service<Request<Full<Bytes>>> for CachingService {
    type Response = Response<Full<Bytes>>;
    type Error = Box<dyn std::error::Error + Send + Sync>;
    type Future = std::pin::Pin<Box<dyn std::future::Future<Output = Result<Self::Response, Self::Error>> + Send>>;

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

    fn call(&mut self, req: Request<Full<Bytes>>) -> Self::Future {
        let manager = self.cache_manager.clone();
        Box::pin(async move {
            // Cache logic using the manager would go here
            let response = Response::builder()
                .status(StatusCode::OK)
                .body(Full::new(Bytes::from("Hello from cached service!")))?;
            Ok(response)
        })
    }
}

With Hyper

use hyper::{Request, Response, StatusCode, body::Incoming};
use http_body_util::Full;
use bytes::Bytes;
use http_cache_quickcache::QuickManager;
use std::convert::Infallible;

async fn handle_request(
    _req: Request<Incoming>,
    cache_manager: QuickManager,
) -> Result<Response<Full<Bytes>>, Infallible> {
    // Use cache_manager here for caching responses
    Ok(Response::builder()
        .status(StatusCode::OK)
        .header("cache-control", "max-age=3600")
        .body(Full::new(Bytes::from("Hello from Hyper with caching!")))
        .unwrap())
}
