Trait Implementations

impl<'a, Coord, DB: DrawingBackend> PointCollection<'a, Coord> for &'a EmptyElement<Coord, DB>[+]

[+] Show hidden undocumented items

type Borrow = &'a Coord

The item in point iterator

type IntoIter = Once<&'a Coord>

The point iterator

fn point_iter(self) -> Self::IntoIter[−]

framework to do the coordinate mapping

impl<Coord, DB: DrawingBackend> Drawable<DB> for EmptyElement<Coord, DB>[+]

[+] Show hidden undocumented items

fn draw<I: Iterator<Item = BackendCoord>>(
    &self,
    _pos: 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

    Other: Drawable<DB>,
    &'a Other: PointCollection<'a, BackendCoord>, [+]

type Output = BoxedElement<Coord, DB, Other>

The resulting type after applying the + operator.

fn add(self, other: Other) -> Self::Output[−]

Performs the + operation.
