Enum DrawCmd 

pub enum DrawCmd {
    Rect {
        rect: Rect,
        color: Color,
        radius: f64,
        border: f64,
    },
    Text {
        text: String,
        origin: Point,
        size: f64,
        color: Color,
    },
    PushClip(Rect),
    PopClip,
    Viewport {
        rect: Rect,
        id: u64,
    },
}

A structured record of a scene primitive, kept alongside the lowered oxideav nodes so a GPU backend can consume the scene without re-deriving primitives from vector paths (the CPU rasterizer uses the nodes; the GPU path uses these). See Scene::commands.

Variants

Rect

A box: radius rounds the corners (0 = sharp); border > 0 strokes the outline at that width instead of filling.

Fields

rect: Rect

color: Color

radius: f64

border: f64

Text

A single line of text at origin (top-left).

Fields

text: String

origin: Point

size: f64

color: Color

PushClip(Rect)

Begin clipping subsequent primitives to rect (nests until PopClip). GPU backends map this to a scissor rectangle.

PopClip

End the innermost clip region opened by PushClip.

Viewport

A reserved area for embedded content (a browser page, video, or any externally-rendered surface), identified by id. The compositor draws the content here: the CPU path blits the registered content [Pixmap] over the placeholder fill after rasterizing; a GPU backend samples the imported (dma-buf / IOSurface / shared-handle) texture into this rect. See Scene::fill_viewport.

Fields

rect: Rect

id: u64

Trait Implementations

impl Clone for DrawCmd

fn clone(&self) -> DrawCmd

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DrawCmd

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

Formats the value using the given formatter.

impl PartialEq for DrawCmd

fn eq(&self, other: &DrawCmd) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
