Struct Path 

pub struct Path { /* private fields */ }

An immutable set of contours.

Flattening the curves into polylines (Path::to_contours) is memoized: a path filled repeatedly with the same transform and tolerance — the common case for a shape redrawn every frame — reuses the cached polylines instead of re-flattening and re-allocating them. The cache uses interior mutability, so a Path is Send but not Sync (single-threaded use, as elsewhere in the crate); equality and Debug ignore it.

Implementations

impl Path

pub fn segments(&self) -> &[PathSegment]

The contour segments.

pub fn is_empty(&self) -> bool

Whether the path is empty.

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

Bounding box over the anchor points (without accounting for curve bending).

Trait Implementations

impl Clone for Path

fn clone(&self) -> Self

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.

impl PartialEq for Path

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
