Struct EffectBuilder 

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

Builder shared by every effect: pipeline knobs pass through to WgpuFrameFilterBuilder, the shader and params type stay fixed.

Implementations

impl<P: Pod> EffectBuilder<P>

pub fn params(self, params: P) -> Self

Replaces the initial parameter value.

pub fn output_size(self, width: u32, height: u32) -> Self

Output frame size; defaults to the input size. See WgpuFrameFilterBuilder::output_size.

pub fn frames_in_flight(self, count: usize) -> Self

GPU/CPU overlap depth (1..=4). See WgpuFrameFilterBuilder::frames_in_flight.

pub fn zero_copy_readback(self, enabled: bool) -> Self

Experimental zero-copy readback. See WgpuFrameFilterBuilder::zero_copy_readback.

pub fn hw_zero_copy_input(self, enabled: bool) -> Self

Experimental dmabuf import of hardware frames. See WgpuFrameFilterBuilder::hw_zero_copy_input.

pub fn build(self) -> Result<Effect<P>, WgpuFilterError>
