Struct librashader_runtime_wgpu::FilterChainWgpu

pub struct FilterChainWgpu { /* private fields */ }

A wgpu filter chain.

Implementations

impl FilterChainWgpu

pub fn load_from_path( path: impl AsRef<Path>, device: Arc<Device>, queue: Arc<Queue>, options: Option<&FilterChainOptionsWgpu> ) -> Result<FilterChainWgpu>

Load the shader preset at the given path into a filter chain.

pub fn load_from_preset( preset: ShaderPreset, device: Arc<Device>, queue: Arc<Queue>, options: Option<&FilterChainOptionsWgpu> ) -> Result<FilterChainWgpu>

Load a filter chain from a pre-parsed ShaderPreset.

pub fn load_from_preset_deferred( preset: ShaderPreset, device: Arc<Device>, queue: Arc<Queue>, cmd: &mut CommandEncoder, options: Option<&FilterChainOptionsWgpu> ) -> Result<FilterChainWgpu>

Load a filter chain from a pre-parsed ShaderPreset, deferring and GPU-side initialization to the caller. This function therefore requires no external synchronization of the device queue.

Safety

The provided command buffer must be ready for recording and contain no prior commands. The caller is responsible for ending the command buffer and immediately submitting it to a graphics queue. The command buffer must be completely executed before calling frame.

pub fn frame<'a>( &mut self, input: Arc<Texture>, viewport: &Viewport<'_, WgpuOutputView<'a>>, cmd: &mut CommandEncoder, frame_count: usize, options: Option<&FrameOptionsWgpu> ) -> Result<()>

Records shader rendering commands to the provided command encoder.
