Struct Path 

pub struct Path { /* private fields */ }

A 2-D path storing a sequence of draw commands.

Use PathBuilder (or the inherent builder methods) to populate a path, then call Path::fill or Path::stroke to rasterise it.

Implementations

impl Path

pub fn new() -> Self

Create an empty path with the default (non-zero) fill rule.

pub fn with_fill_rule(self, rule: FillRule) -> Self

Set the fill rule (consumes and returns self for chaining).

pub fn move_to(&mut self, p: Point) -> &mut Self

Move the current point to p without drawing.

pub fn line_to(&mut self, p: Point) -> &mut Self

Add a straight line from the current point to p.

pub fn quad_to(&mut self, ctrl: Point, end: Point) -> &mut Self

Add a quadratic Bézier curve with control point ctrl ending at end.

pub fn cubic_to(&mut self, c1: Point, c2: Point, end: Point) -> &mut Self

Add a cubic Bézier curve with control points c1/c2 ending at end.

pub fn close(&mut self) -> &mut Self

Close the current sub-path (draw a line back to the last MoveTo).

pub fn flatten(&self, tolerance: f32) -> Vec<Vec<Point>>

Flatten all sub-paths to sequences of line vertices.

Returns one Vec<Point> per sub-path (contour). The last point of each contour is not duplicated at the start; callers should treat the contour as closed (connect last → first).

tolerance is the maximum chord-distance deviation allowed per Bézier segment (in pixels). A value of 0.25 gives visually smooth curves.

pub fn fill(&self, fb: &mut Framebuffer, color: Color)

Fill this path’s interior into fb using the configured fill rule.

A single Rasterizer is created for the duration of this call so that scratch buffers are reused across all contours of the path.

pub fn stroke(&self, fb: &mut Framebuffer, style: &StrokeStyle, color: Color)

Stroke this path into fb using the given style.

Each sub-path is stroked independently; closed sub-paths produce closed outlines (the cap style is ignored for closed paths).

A single Rasterizer is created for the duration of this call so that scratch buffers are reused across all contours.

pub fn fill_clipped(&self, fb: &mut Framebuffer, color: Color, clip: ClipRect)

Fill this path’s interior, clipped to clip.

Uses fill_polygon_clipped so pixels outside clip are never written. Anti-aliasing is enabled by default.

pub fn stroke_clipped( &self, fb: &mut Framebuffer, style: &StrokeStyle, color: Color, clip: ClipRect, )

Stroke this path, clipped to clip.

Constructs the stroke polygon and fills it using fill_polygon_clipped.

pub fn fill_clipped_aa( &self, fb: &mut Framebuffer, color: Color, clip: ClipRect, aa: bool, )

Fill this path’s interior, clipped to clip, with explicit AA control.

When aa is false, edges are aliased (faster; no coverage blending).

A single Rasterizer is created for the duration of this call so that scratch buffers are reused across all contours.

pub fn stroke_clipped_aa( &self, fb: &mut Framebuffer, style: &StrokeStyle, color: Color, clip: ClipRect, aa: bool, )

Stroke this path, clipped to clip, with explicit AA control.

When aa is false, the stroke polygon edges are aliased.

A single Rasterizer is created for the duration of this call so that scratch buffers are reused across all contours.

Trait Implementations

impl Clone for Path

fn clone(&self) -> Path

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Path

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

Formats the value using the given formatter.

impl Default for Path

fn default() -> Path

Returns the “default value” for a type.
