Shutdown and Draining

The default behavior of most SDKs is to send out events over the network asynchronously in the background. This means that some events might be lost if the application shuts down unexpectedly. The SDKs provide 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() {

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