👎Deprecated: use the EventHandler API

Expand description

Usage of this trait is deprecated. Applications should use the EventHandler API.

Applications can implement this trait to specify custom logic to run on each command event sent by the driver.

struct FailedCommandLogger;

impl CommandEventHandler for FailedCommandLogger {
    fn handle_command_failed_event(&self, event: CommandFailedEvent) {
        eprintln!("Failed command: {:?}", event);
    }
}

let handler = Arc::new(FailedCommandLogger);
let options = ClientOptions::builder()
                  .command_event_handler(handler)
                  .build();
let client = Client::with_options(options)?;

// Do things with the client, and failed command events will be logged to stderr.
