Struct ShaderDraw 

pub struct ShaderDraw {
    pub order: DrawOrder,
    pub bounds: Bounds<ScaledPixels>,
    pub content_mask: ContentMask<ScaledPixels>,
    pub opacity: f32,
    pub scale_factor: f32,
    pub program: Arc<SceneShaderProgram>,
    pub glyph_mask: Option<AtlasTile>,
    pub path_mask: Option<Arc<Path<ScaledPixels>>>,
    pub data: [[f32; 4]; 8],
}

Immutable instance recorded into a scene and retained through paint replay.

Fields

order: DrawOrder

Host draw order, assigned on insertion.

bounds: Bounds<ScaledPixels>

Full source bounds in device pixels, including any effect outset.

content_mask: ContentMask<ScaledPixels>

Host clipping in device pixels.

opacity: f32

Inherited element opacity, applied exactly once by the generated wrapper.

scale_factor: f32

Logical-to-device scale used for shader coordinates.

program: Arc<SceneShaderProgram>

Immutable program handle.

glyph_mask: Option<AtlasTile>

Optional retained grayscale atlas tile. Masked programs batch by texture.

path_mask: Option<Arc<Path<ScaledPixels>>>

Native opaque-white coverage, rasterized into the existing path target. Disjoint composite bounds can share a coverage/composition batch.

data: [[f32; 4]; 8]

Reflected and packed payload. Unused slots are zero.

Implementations

impl ShaderDraw

pub fn validate_masks(&self) -> Result<()>

Check mask ownership before preparing backend resources.

pub fn instance_data(&self) -> [[f32; 4]; 11]

Transport layout: bounds, clip, opacity/scale, then payload; 176 bytes.

Trait Implementations

impl Clone for ShaderDraw

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ShaderDraw

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
