Required Methods§

fn OnDisplayNameChanged( &self, newdisplayname: &PCWSTR, eventcontext: *const GUID, ) -> Result<()>

fn OnIconPathChanged( &self, newiconpath: &PCWSTR, eventcontext: *const GUID, ) -> Result<()>

fn OnSimpleVolumeChanged( &self, newvolume: f32, newmute: BOOL, eventcontext: *const GUID, ) -> Result<()>

fn OnChannelVolumeChanged( &self, channelcount: u32, newchannelvolumearray: *const f32, changedchannel: u32, eventcontext: *const GUID, ) -> Result<()>

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.
