Struct Effect 

pub struct Effect<P: Pod> { /* private fields */ }

A built-in effect: a WgpuFrameFilter whose parameter type is fixed at build time, so Self::params_handle needs no type argument and cannot be mismatched against a same-sized foreign struct.

Implements FrameFilter by delegation — box it straight into a pipeline: pipeline.filter("adjust", Box::new(effect)).

Implementations

impl<P: Pod> Effect<P>

pub fn params_handle(&self) -> WgpuParamsHandle<P>

Typed handle for live parameter updates from any thread.

pub fn stats_handle(&self) -> Arc<Mutex<WgpuFilterStats>>

Shared handle to cumulative per-stage timing statistics.

pub fn into_inner(self) -> WgpuFrameFilter

Unwraps the underlying WgpuFrameFilter, giving up the typed params binding.

Trait Implementations

impl<P: Pod + Send> FrameFilter for Effect<P>

fn media_type(&self) -> AVMediaType

Returns the media type this filter operates on.

fn init( &mut self, ctx: &mut FrameFilterContext<'_>, ) -> Result<(), FrameFilterError>

Initializes the filter.

fn filter_frame( &mut self, frame: Frame, ctx: &mut FrameFilterContext<'_>, ) -> Result<Option<Frame>, FrameFilterError>

Processes a single frame through the filter.

fn request_frame( &mut self, ctx: &mut FrameFilterContext<'_>, ) -> Result<Option<Frame>, FrameFilterError>

Requests a frame from the filter.

fn request_frame_mode(&self) -> RequestFrameMode

Declares whether request_frame can produce frames autonomously. Returning RequestFrameMode::Never lets the pipeline stop polling this filter (PERF-8). The default preserves the historical always-polled behavior for third-party generator filters.

fn uninit(&mut self, ctx: &mut FrameFilterContext<'_>)

Cleans up the filter.
