Variants

Content

Marker emitted by draw_content() inside draw_with_content. This is consumed by the modifier pipeline and never rendered directly.

Blend

Wrapper to associate a draw primitive with a non-default blend mode.

Fields

primitive: Box<DrawPrimitive>

blend_mode: BlendMode

Rect

Fields

rect: Rect

brush: Brush

stroke: Option<Stroke>

None fills the rect; Some strokes its outline, centered on the edge (so it bleeds width / 2 outside rect).

RoundRect

Fields

rect: Rect

brush: Brush

radii: CornerRadii

stroke: Option<Stroke>

None fills the rounded rect; Some strokes its outline, centered on the edge.

Arc

A circular band: a stroked arc, or a filled annular sector / pie wedge.

Angles are radians, 0 = +X, increasing clockwise on screen (see [crate::stroke] for the full convention).

• stroke = Some(_) — the band is radius ± width/2, its ends shaped by the stroke cap. inner_radius is ignored.
• stroke = None — the band is inner_radius ..= radius with flat (butt) radial ends; inner_radius = 0 is a filled pie wedge.

Fields

rect: Rect

Tight bounding box of the rendered band, caps included. Kept as the first field (like every other variant) so bbox/culling/clip logic treats an arc exactly like any other primitive.

brush: Brush

center: Point

radius: f32

start_angle: f32

sweep_angle: f32

stroke: Option<Stroke>

inner_radius: f32

> 0 turns a filled wedge into an annular sector.

Image

Fields

rect: Rect

image: ImageBitmap

alpha: f32

color_filter: Option<ColorFilter>

sampling: ImageSampling

src_rect: Option<Rect>

Optional source rectangle in image-pixel coordinates. When None, the entire image is drawn. When Some, only the specified sub-region of the source image is sampled.

Text(Box<TextPrimitive>)

A laid-out run of text. See TextPrimitive.

Shadow(ShadowPrimitive)

Shadow that requires blur processing. The renderer decides technique (GPU blur, CPU approximation, etc.).
