Struct Circle

pub struct Circle<'a, Coord> { /* private fields */ }

A circle element

Implementations

impl<'a, Coord> Circle<'a, Coord>

pub fn new<S: Into<ShapeStyle<'a>>>(coord: Coord, size: u32, 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<'a, Coord: 'a, DB: DrawingBackend> Drawable<DB> for Circle<'a, Coord>

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

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

impl<'b, 'a, Coord: 'a> PointCollection<'a, Coord> for &'a Circle<'b, Coord>

type Borrow = &'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<'a, Coord> PointElement<'a, Coord> for Circle<'a, Coord>

fn make_point(pos: Coord, size: u32, style: ShapeStyle<'a>) -> Self
