Trait Implementations

impl<Coord: Clone, Size: Clone + SizeDesc> Clone for TriangleArrow<Coord, Size>

fn clone(&self) -> TriangleArrow<Coord, Size>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<DB: DrawingBackend, Coord, Size: SizeDesc> Drawable<DB> for TriangleArrow<Coord, Size>

fn draw<I: Iterator<Item = BackendCoord>>( &self, pos: I, backend: &mut DB, parent_dim: (u32, u32), ) -> Result<(), DrawingErrorKind<DB::ErrorType>>

Actually draws the element. The key points is already translated into the image coordinate and can be used by DC directly

impl<'a, Coord: 'a, Size: SizeDesc> PointCollection<'a, Coord> for &'a TriangleArrow<Coord, Size>

type Point = &'a Coord

The item in point iterator

type IntoIter = &'a [Coord]

The point iterator

fn point_iter(self) -> Self::IntoIter

framework to do the coordinate mapping
