Implementors

StreamVolume

Provided Methods

fn is_muted(&self) -> bool

Returns

Returns true if the stream is muted

fn volume(&self, format: StreamVolumeFormat) -> f64

format

StreamVolumeFormat which should be returned

Returns

The current stream volume as linear factor

fn set_mute(&self, mute: bool)

mute

Mute state that should be set

fn set_volume(&self, format: StreamVolumeFormat, val: f64)

format

StreamVolumeFormat of val

val

Linear volume factor that should be set

fn connect_mute_notify<F: Fn(&Self) + Send + Sync + 'static>( &self, f: F, ) -> SignalHandlerId

fn connect_volume_notify<F: Fn(&Self) + Send + Sync + 'static>( &self, f: F, ) -> SignalHandlerId
