Struct Polygon

pub struct Polygon<Coord> { /* private fields */ }

An element of a filled polygon

Implementations

impl<Coord> Polygon<Coord>

pub fn new<P: Into<Vec<Coord>>, S: Into<ShapeStyle>>( points: P, style: S, ) -> Self

Create a new polygon

• points: The iterator of the points
• style: The shape style
• returns the created element

Trait Implementations

impl<Coord, DB: DrawingBackend> Drawable<DB> for Polygon<Coord>

fn draw<I: Iterator<Item = BackendCoord>>( &self, points: I, backend: &mut DB, _: (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> PointCollection<'a, Coord> for &'a Polygon<Coord>

type Point = &'a Coord

The item in point iterator

type IntoIter = &'a [Coord]

The point iterator

fn point_iter(self) -> &'a [Coord]

framework to do the coordinate mapping
