Struct BezierPath 

pub struct BezierPath { /* private fields */ }

A mixed straight/cubic Bézier path with dash-point metadata on its vertices.

vertex_is_dash_point contains one entry for the initial vertex followed by one entry for every segment end, so its length is always geometry.num_segments() + 1. For a closed path, its first and final entries describe the same seam vertex and therefore have the same value.

Implementations

impl BezierPath

pub fn geometry(&self) -> &BezierString

Get the mixed straight/cubic geometry.

pub fn vertex_is_dash_point(&self) -> &[bool]

Get the dash-point state of the initial vertex and every segment end.

pub fn map_coords(self, transform: impl Fn(Coord) -> Coord) -> Self

Transform every endpoint and Bézier handle while preserving path topology and dash-point metadata.

transform should map equal coordinates to equal coordinates, as coordinate reprojection functions normally do.

pub fn into_parts(self) -> (BezierString, Vec<bool>)

Consume the path and return its geometry and vertex dash flags.

pub fn segments(&self) -> impl ExactSizeIterator<Item = (&BezierSegment, bool)>

Iterate over segments paired with the dash-point state of their end vertices.

The initial vertex’s state is available as vertex_is_dash_point().first().

Trait Implementations

impl Clone for BezierPath

fn clone(&self) -> BezierPath

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BezierPath

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

Formats the value using the given formatter.
