Struct plotters::element::ComposedElement

pub struct ComposedElement<Coord, DB: DrawingBackend, A, B>where
    A: Drawable<DB>,
    B: Drawable<DB>,{ /* private fields */ }

A container for two drawable elements, used for composition.

This is used internally by Plotters and should probably not be included in user code. See EmptyElement for more information and examples.

Trait Implementations

impl<Coord, DB: DrawingBackend, A, B, C> Add<C> for ComposedElement<Coord, DB, A, B>where A: Drawable<DB>, for<'a> &'a A: PointCollection<'a, BackendCoord>, B: Drawable<DB>, for<'a> &'a B: PointCollection<'a, BackendCoord>, C: Drawable<DB>, for<'a> &'a C: PointCollection<'a, BackendCoord>,

type Output = ComposedElement<Coord, DB, A, ComposedElement<(i32, i32), DB, B, C>>

The resulting type after applying the + operator.

fn add(self, rhs: C) -> Self::Output

Performs the + operation.

impl<Coord, DB: DrawingBackend, A, B> Drawable<DB, BackendCoordOnly> for ComposedElement<Coord, DB, A, B>where for<'a> &'a A: PointCollection<'a, BackendCoord>, for<'b> &'b B: PointCollection<'b, BackendCoord>, A: Drawable<DB>, B: Drawable<DB>,

fn draw<I: Iterator<Item = BackendCoord>>( &self, pos: 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<'b, Coord, DB: DrawingBackend, A, B> PointCollection<'b, Coord, BackendCoordOnly> for &'b ComposedElement<Coord, DB, A, B>where A: Drawable<DB>, B: Drawable<DB>,

type Point = &'b Coord

The item in point iterator

type IntoIter = Once<&'b Coord>

The point iterator

fn point_iter(self) -> Self::IntoIter

framework to do the coordinate mapping
