Elegant Departure

Rust crate to simplify graceful async shutdowns:

• Easy to use with a minimal API
• Runtime independent (works with tokio, async-std, smol, …)
• Additional integrations for tokio (shutdown on ctrl-c, signals etc.)

Usage

This crate is on crates.io and can be used by adding it to your dependencies in your project's Cargo.toml.

toml [dependencies] elegant-departure = "0.2"

For a optional tokio integration, you need to enable the tokio feature:

toml [dependencies] elegant-departure = { version = "0.2", features = "tokio" }

Example

Examples can be found in the example directory:

• Simple: simple example without tokio integration
• Tokio: Tokio integration example
• Hyper: a shutdown example using the Hyper webserver
• Worker: example implementation of a worker using select!
• Smol: example using the smol runtime
• Async Std: example using the async_std runtime

Minimal example using the tokio integration:

```rust use std::time::Duration;

async fn worker(name: &'static str) { let guard = elegantdeparture::getshutdown_guard();

println!("[{}] working", name);

guard.wait().await;
println!("[{}] shutting down", name);

tokio::time::sleep(Duration::from_secs(1)).await;
println!("[{}] done", name);

}

[tokio::main]

async fn main() { tokio::spawn(worker("worker 1")); tokio::spawn(worker("worker 2"));

elegant_departure::tokio::depart()
    // Shutdown on Ctrl+C and SIGTERM
    .on_termination()
    .await

} ```
