Struct PathSlice

pub struct PathSlice<'l> { /* private fields */ }

Available on crate feature canvas only.

A view on a Path.

Implementations

impl<'l> PathSlice<'l>

An immutable view over a Path.

pub fn first_endpoint(&self) -> Option<(Point2D<f32, UnknownUnit>, &'l [f32])>

pub fn last_endpoint(&self) -> Option<(Point2D<f32, UnknownUnit>, &'l [f32])>

pub fn iter<'a>(&'a self) -> Iter<'l>

Iterates over the path.

pub fn id_iter(&self) -> IdIter<'_>

Iterates over the endpoint and control point ids of the Path.

pub fn iter_with_attributes(&self) -> IterWithAttributes<'_>

Iterates over the entire Path with custom attributes.

pub fn is_empty(&self) -> bool

pub fn attributes(&self, endpoint: EndpointId) -> &'l [f32]

Returns a slice over an endpoint’s custom attributes.

pub fn reversed(&self) -> NoAttributes<Reversed<'_>>

Returns a reversed version of this path in the form of an iterator
