Struct VolumeEffects 

pub struct VolumeEffects<'a, 'b, S: AppState> { /* private fields */ }

Convenience builder for standard volume-control host capabilities.

Implementations

impl<'a, 'b, S: AppState> VolumeEffects<'a, 'b, S>

pub fn get_level(self, stream: VolumeStream) -> EffectBuilder<'a, 'b, S>

Reads the current level for one host volume stream.

stream identifies the logical audio stream the app cares about. Hosts map that stream to the closest platform mixer or media channel and return a VolumeLevel with level and mute state.

pub fn set_level(self, request: VolumeSetRequest) -> EffectBuilder<'a, 'b, S>

Sets the level and optional mute state for one host volume stream.

request.level is a percentage-like value from 0 to 100. Hosts should clamp or reject values they cannot represent and return a typed error when the platform does not expose system volume control.

pub fn adjust_level( self, request: VolumeAdjustRequest, ) -> EffectBuilder<'a, 'b, S>

Adjusts a host volume stream relative to its current level.

request.direction chooses increase, decrease, or toggle mute, and request.step controls the requested amount. Use this for keyboard-like or remote-control volume actions.
