Struct Rect 

pub struct Rect {
    pub x: i32,
    pub y: i32,
    pub width: i32,
    pub height: i32,
}

Rectangle bounds of a widget.

Coordinates are relative to the parent widget. Width and height are signed integers to simplify layout calculations.

Used by Widget implementations to describe layout and passed to Renderer::fill_rect when drawing.

Fields

x: i32

X coordinate relative to the parent widget.

y: i32

Y coordinate relative to the parent widget.

width: i32

Width in pixels.

height: i32

Height in pixels.

Implementations

impl Rect

pub fn union(self, other: Rect) -> Rect

Axis-aligned bounding box of self and other.

Mirrors the union semantics of CommandList::dirty_union and the anim registry’s dirty-rect bookkeeping.

pub fn intersect(self, other: Rect) -> Option<Rect>

Axis-aligned intersection of self and other, or None when the rects are disjoint or the overlap is degenerate (zero/negative area).

Companion to union; used by ClipRenderer to fold nested clip regions and crop forwarded draws.

pub fn lerp(self, to: Rect, num: i32, den: i32) -> Rect

Integer linear interpolation from self toward to by num / den.

Each field is interpolated as a + (b - a) * num / den using i64 intermediates (truncation toward zero). Deterministic — no floats.
