Struct ShaderChain 

pub struct ShaderChain { /* private fields */ }

An ordered list of shader effects applied to captured content.

Each pass receives the previous pass output as a texture target. A pass that is not registered is skipped and its input is forwarded to the next pass. If the final pass is missing, the captured layer is blitted back unchanged, so a missing optional effect degrades instead of blanking the layer.

Implementations

impl ShaderChain

pub fn new() -> Self

pub fn effect<S: SequoiShader + Copy + 'static>(self, shader: S) -> Self

Appends an effect that binds the shader’s first declared texture.

pub fn effect_with_blend<S: SequoiShader + Copy + 'static>( self, shader: S, blend: BlendMode, ) -> Self

Appends an effect with an explicit blend mode.

pub fn effect_to<S: SequoiShader + Copy + 'static>( self, shader: S, input: &'static str, blend: Option<BlendMode>, ) -> Self

Appends an effect that binds input to a named texture parameter.

pub fn extend(&mut self, other: ShaderChain)

Appends every pass from other after the current ones.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool
