Implementations§

Source§

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

Source

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§

Source§

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

Source§

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> for &'a Circle<Coord, Size>

Source§

type Point = &'a Coord

The item in point iterator
Source§

type IntoIter = Once<&'a Coord>

The point iterator

Layout§

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
