Struct lyon_algorithms::walk::PathWalker

pub struct PathWalker<'l> { /* fields omitted */ }

A helper struct to walk along a flattened path using a builder API.

Methods

impl<'l> PathWalker<'l>

pub fn new(start: f32, pattern: &'l mut Pattern) -> PathWalker<'l>

Trait Implementations

impl<'l> FlatPathBuilder for PathWalker<'l>

type PathType = ()

The type of object that is created by this builder.

fn move_to(&mut self, to: Point)

Sets the current position in preparation for the next sub-path. If the current sub-path contains edges, this ends the sub-path without closing it.

fn line_to(&mut self, to: Point)

Adds a line segment to the current sub-path and set the current position.

fn close(&mut self)

Closes the current sub path and sets the current position to the first position of this the current sub-path.

fn build(self)

Builds a path object and resets the builder so that it can be used again.

fn build_and_reset(&mut self)

Builds a path object and resets the builder so that it can be used again.

fn current_position(&self) -> Point

fn flat_event(&mut self, event: FlattenedEvent)

fn flattened(self, tolerance: f32) -> FlatteningBuilder<Self>

Returns a builder that approximates all curves with sequences of line segments.
