Expand description

Trait containing all StreamVolume methods.

§Implementors

StreamVolume

Provided Methods§

Source

fn is_muted(&self) -> bool

§Returns

Returns true if the stream is muted

Source

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

§format

StreamVolumeFormat which should be returned

§Returns

The current stream volume as linear factor

Source

fn set_mute(&self, mute: bool)

§mute

Mute state that should be set

Source

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

§format

StreamVolumeFormat of val

§val

Linear volume factor that should be set

Source

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

Source

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

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
