Enum Shape 

pub enum Shape {
    Rect(Rect),
    RoundedRect(Rect, f64),
    Ellipse(Rect),
    Arc {
        rect: Rect,
        start_deg: f64,
        sweep_deg: f64,
    },
    Line(Point, Point),
    Polygon(Vec<Point>),
    Path(Path),
}

Variants

Rect(Rect)

RoundedRect(Rect, f64)

Ellipse(Rect)

Arc

Arc within rect’s inscribed ellipse; angles in degrees, 0 = +x axis, clockwise.

Fields

rect: Rect

start_deg: f64

sweep_deg: f64

Line(Point, Point)

Polygon(Vec<Point>)

Path(Path)

An arbitrary path: curves, several contours, and a fill rule (docs/canvas.md).

Shape::Polygon is the straight-line, single-contour special case, kept because it is what most drawing code wants and it encodes far more compactly.

Implementations

impl Shape

pub fn rounded_rect(rect: Rect, radii: CornerRadii) -> Shape

A rectangle rounded corner by corner (docs/canvas.md “Rounded corners”), as the simplest shape that draws it: a plain Shape::Rect when every corner is square, a Shape::RoundedRect (each toolkit’s own rounded rectangle) when the corners agree, and a path (rounded_rect_segs) otherwise. The radii are fitted first.

use day_spec::{CornerRadii, Rect, Shape};

// A bar standing on its axis: rounded on top, square where it meets the baseline.
let bar = Shape::rounded_rect(Rect::new(0.0, 0.0, 20.0, 80.0), CornerRadii::top(6.0));
assert!(matches!(bar, Shape::Path(_)));

pub fn translated(&self, dx: f64, dy: f64) -> Shape

The same shape moved by (dx, dy).

What a Stamp means by “the template translated by one point”, and the one definition of it: a backend builds each copy of a batch with this rather than reaching for its own platform transform, so every toolkit stamps to the same coordinates.

pub fn bounds(&self) -> Rect

The shape’s bounding rectangle: the box gradient UnitPoints resolve against.
