Struct plotters::element::Circle

pub struct Circle<Coord, Size: SizeDesc> { /* private fields */ }

A circle element

Implementations

impl<Coord, Size: SizeDesc> Circle<Coord, Size>

pub fn new<S: Into<ShapeStyle>>(coord: Coord, size: Size, style: S) -> Self

Create a new circle element

• coord The center of the circle
• size The radius of the circle
• style The style of the circle
• Return: The newly created circle element

Trait Implementations

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

fn draw<I: Iterator<Item = BackendCoord>>( &self, points: I, backend: &mut DB, ps: (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, Size: SizeDesc> PointCollection<'a, Coord, BackendCoordOnly> for &'a Circle<Coord, Size>

type Point = &'a Coord

The item in point iterator

type IntoIter = Once<&'a Coord>

The point iterator

fn point_iter(self) -> Once<&'a Coord>

framework to do the coordinate mapping

impl<Coord, Size: SizeDesc> PointElement<Coord, Size> for Circle<Coord, Size>

fn make_point(pos: Coord, size: Size, style: ShapeStyle) -> Self

Point creator.
