Struct DottedPathElement

pub struct DottedPathElement<I: Iterator + Clone, Size: SizeDesc, Marker> { /* private fields */ }

An element of a series of connected lines in dot style for any markers.

It’s similar to PathElement but use a marker function to draw markers with spacing.

Implementations

impl<I: Iterator + Clone, Size: SizeDesc, Marker> DottedPathElement<I, Size, Marker>

pub fn new<I0, F>(points: I0, shift: Size, spacing: Size, func: F) -> Self

where I0: IntoIterator<IntoIter = I>, F: Fn(BackendCoord) -> Marker + 'static,

Create a new path

• points: The iterator of the points
• shift: The shift of the first marker
• spacing: The spacing between markers
• func: The marker function
• returns the created element

Trait Implementations

impl<I0, Size, DB, Marker> Drawable<DB> for DottedPathElement<I0, Size, Marker>

where I0: Iterator + Clone, Size: SizeDesc, DB: DrawingBackend, Marker: IntoDynElement<'static, DB, BackendCoord>,

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, I: Iterator + Clone, Size: SizeDesc, Marker> PointCollection<'a, <I as Iterator>::Item> for &'a DottedPathElement<I, Size, Marker>

type Point = <I as Iterator>::Item

The item in point iterator

type IntoIter = I

The point iterator

fn point_iter(self) -> Self::IntoIter

framework to do the coordinate mapping

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.
