Struct Path 

pub struct Path { /* private fields */ }

Path is an immutable collection of line and Bézier contours.

Build paths with PathBuilder. Display lists retain shared Arc handles, so recording and nesting do not copy path data.

Implementations

impl Path

pub fn bounds(&self) -> Rect

bounds returns conservative control-point bounds.

pub fn tight_bounds(&self) -> Rect

tight_bounds returns exact axis-aligned curve bounds.

pub fn is_empty(&self) -> bool

is_empty reports whether the path contains no commands.

pub fn heap_bytes(&self) -> usize

heap_bytes returns an estimate of owned path storage.

pub fn contains(&self, point: Point, fill_rule: FillRule) -> bool

contains reports whether a point lies inside the filled path.

The query evaluates the original curves, implicitly closes open contours, and treats points on the outline as inside.

pub fn measure(&self, tolerance: f32) -> Vec<ContourMeasure>

measure returns an arc-length measurement for each nonempty contour.

tolerance is the maximum flattening deviation in path coordinates.

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

flatten approximates curves with polygonal contours.

tolerance is the maximum deviation in path coordinates. Fill operations implicitly close every contour; stroke operations use Contour::closed.

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.
