Struct Path 

pub struct Path {
    pub commands: Vec<PathCommand>,
    /* private fields */
}

A path made of PathCommands.

Used by DrawCommand::Fill and DrawCommand::PushClip. The GPU rasterizer converts the path into a polygon with Path::as_polygon_vertices, flattening curved segments into line segments.

Fields

commands: Vec<PathCommand>

Implementations

impl Path

pub fn new() -> Self

Creates an empty path.

pub fn move_to(&mut self, x: f32, y: f32)

Starts a new subpath at (x, y).

pub fn line_to(&mut self, x: f32, y: f32)

Draws a straight line to (x, y).

If the path has no current point yet, the line is treated as a starting point.

pub fn quad_to(&mut self, c: (f32, f32), p: (f32, f32))

Draws a quadratic Bézier curve to p with control point c.

If the path has no current point yet, the curve is dropped and the path is moved to p instead (a curve has no defined start point).

pub fn cubic_to(&mut self, c1: (f32, f32), c2: (f32, f32), p: (f32, f32))

Draws a cubic Bézier curve to p with control points c1 and c2.

If the path has no current point yet, the curve is dropped and the path is moved to p instead (a curve has no defined start point).

pub fn close(&mut self)

Closes the current subpath, returning the current point to the subpath start.

pub fn bounding_box(&self) -> Option<Rect>

Computes the axis-aligned bounding box of the path, or None for an empty path.

Curve bounds include the control points, so they may overestimate the true extent.

pub fn subpaths(&self) -> Vec<Vec<(f32, f32)>>

Returns the path flattened into a list of vertices per subpath, curving segments into line segments.

Each entry is one closed ring (its closing edge back to the first point is implicit). Multiple MoveTos yield multiple rings.

pub fn as_polygon_vertices(&self) -> Option<Vec<(f32, f32)>>

Returns the path as a single flat list of vertices, or None if the path has fewer than three vertices total.

Prefer Path::subpaths when subpaths must be triangulated independently.

pub fn commands(&self) -> &[PathCommand]

Trait Implementations
