Function svc_compliance::shutdown_signal

pub async fn shutdown_signal(server: &str, shutdown_rx: Option<Receiver<()>>)

Tokio signal handler that will wait for a user to press CTRL+C. This signal handler can be used in our tonic::transport::Server method serve_with_shutdown.

Examples

tonic

use svc_compliance::shutdown_signal;
pub async fn server() {
    let (_, health_service) = tonic_health::server::health_reporter();
    tonic::transport::Server::builder()
        .add_service(health_service)
        .serve_with_shutdown("0.0.0.0:50051".parse().unwrap(), shutdown_signal("grpc", None));
}

using a shutdown signal channel

use svc_compliance::shutdown_signal;
pub async fn server() {
    let (shutdown_tx, shutdown_rx) = tokio::sync::oneshot::channel::<()>();
    let (_, health_service) = tonic_health::server::health_reporter();
    tokio::spawn(async move {
        tonic::transport::Server::builder()
            .add_service(health_service)
            .serve_with_shutdown("0.0.0.0:50051".parse().unwrap(), shutdown_signal("grpc", Some(shutdown_rx)))
            .await;
    });

    // Send server the shutdown request
    shutdown_tx.send(()).expect("Could not stop server.");
}
