rocket included as a dependency about rust-actuator

[moray95]

Hello @dizda, thanks your interest. The core of this library is to expose an http server with easy with different endpoints and use Rocket for this. I don't think it's really possible to have Rocket as an optional dependency. What is your use-case so that you don't need Rocket?

Ah makes sense.

I simply use this library to collect gRPC data on my existing prometheus endpoint.

cf.

    let provider_server = ProviderServiceServer::new(provider_state);

    // setup prometheus gRPC stats
    let config = HttpRequestCollectorConfig::default(pr0m3th3us::get_registry().clone());
    let grpc_prometheus = tower::ServiceBuilder::new()
        .layer(valensas_actuator::prometheus::TonicGrpcCollectorLayer::new(&config).unwrap())
        .into_inner();

    // setup grpc's server with appropriate grpc services
    let grpc_handle = Server::builder()
        .layer(grpc_prometheus)
        .add_service(health_service)
        .add_service(provider_server)
        .serve(addr);

    // If one of the background task fail, we quit
    tokio::select! {
        e = broker_handle => {
            // The first ? is for JoinHandle's result, and the second one for broker::Result (if amqp crash)
            e??;
        }
        e = grpc_handle => {
            // Customer's server has panicked
            e?;
        }
        e = pr0m3th3us::listen(cfg.prometheus_addr) => {
            e?;
        }
    }
