Provided Methods§

Source

fn setup( &self, token: &AudioVisualizerSetupToken<'_>, ) -> Result<(), LoggableError>

Source

fn render( &self, audio_buffer: &BufferRef, video_frame: &mut VideoFrameRef<&mut BufferRef>, ) -> Result<(), LoggableError>

Source

fn decide_allocation(&self, query: &mut Allocation) -> Result<(), LoggableError>

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.
