Struct Walk

pub struct Walk<D> { /* private fields */ }

An iterator like type that walks along a path by arbitrary steps.

Implementations

impl<D> Walk<D>

where D: Iterator<Item = Command> + Clone,

pub fn new(data: impl PathData<Commands = D>) -> Self

Creates a new iterator like type that steps along a path by abitrary distances.

impl<D> Walk<TransformCommands<D>>

where D: Iterator<Item = Command> + Clone,

pub fn with_transform( data: impl PathData<Commands = D>, transform: Transform, ) -> Self

Creates a new iterator like type that steps along a transformed path by abitrary distances.

impl<D> Walk<D>

where D: Iterator + Clone, D::Item: Borrow<Command>,

pub fn step(&mut self, distance: f32) -> Option<(Point, Vector)>

Steps by the specified distance and returns the point at the new location and the normal vector describing the left-ward direction at that point. Returns None if the distance steps beyond the end of the path.

pub fn remaining(&self) -> f32

Returns the remaining distance available to walk on the path.
