Context provided to nodes when they are initialized.

Required Methods

fn add_audio_input(&self) -> AudioInputId

Add an audio input to the node.

fn add_video_input(&self) -> VideoInputId

Add a video input to the node.

fn add_audio_output(&self) -> AudioOutput

Add an audio output to the node.

fn add_video_output(&self) -> VideoOutput

Add a video output to the node.

fn create_to_rgba( &self, video_format: &VideoFormat, colour_space: &ColourSpec, width: usize, height: usize, ) -> ToRGBA

Create a ToRGBA that can be used to load video frames onto the GPU.

fn create_from_rgba( &self, video_format: &VideoFormat, colour_space: &ColourSpec, width: usize, height: usize, interlace: InterlaceMode, ) -> FromRGBA

Create a [’FromRGBA`] that can be used to consume video frames from the GPU.

fn create_to_audio_f32( &self, audio_format: AudioFormat, channel_layout: AudioChannelLayout, ) -> ToAudioF32

Create a ToAudioF32 that can be used to load audio in 32 bit floating-point format.

fn create_from_audio_f32( &self, audio_format: AudioFormat, channel_layout: AudioChannelLayout, ) -> FromAudioF32

Create a FromAudioF32 that can be used to consume 32 bit floating-point audio in other formats.

fn create_process_shader( &self, kernel: RStr<'_>, program_name: RStr<'_>, ) -> ProcessShader

Create a shader from a source string.

• kernel - Shader code.
• program_name - Name of the kernel function.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
