Shutdown and Draining

By default the SDK sends out events over the network on a background thread. This means that some events might be lost if the application shuts down unexpectedly. The SDK provides mechanisms to cope with this.

When the Rust SDK initializes a guard is returned from the init function. The destructor will automatically wait shutdown_timeout seconds. This means you just need to hold on to the guard and make sure it disposes on shutdown. Alternatively the client can be closed:

use std::time::Duration;

if let Some(client) = sentry::Hub::current().client() {
    client.close(Some(Duration::from_secs(2)));
}

After a call to close, the client cannot be used anymore. It's important to only call close immediately before shutting down the application.
