Required Methods§

fn GetChannelCount(&self) -> Result<u32>

fn GetLevelRange( &self, nchannel: u32, pfminleveldb: *mut f32, pfmaxleveldb: *mut f32, pfstepping: *mut f32, ) -> Result<()>

fn GetLevel(&self, nchannel: u32) -> Result<f32>

fn SetLevel( &self, nchannel: u32, fleveldb: f32, pguideventcontext: *const GUID, ) -> Result<()>

fn SetLevelUniform( &self, fleveldb: f32, pguideventcontext: *const GUID, ) -> Result<()>

fn SetLevelAllChannels( &self, alevelsdb: *const f32, cchannels: u32, pguideventcontext: *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.
