Source 
pub struct ControlMonitor<'d> { /* private fields */ }
Expand description

Control status change monitor

Await ControlMonitor::changed for being notified of configuration changes. Afterwards, the updated configuration settings can be read with ControlMonitor::volume and ControlMonitor::sample_rate_hz.
