Struct flo_canvas::Canvas

pub struct Canvas { /* private fields */ }

A canvas is an abstract interface for drawing graphics. It doesn’t actually provide a means to render anything, but rather a way to describe how things should be drawn and pass those on to a renderer elsewhere.

A canvas can be cloned and sent between threads, so it’s possible for multiple sources to write to the same drawing target.

Canvases maintain a copy of enough of the drawing instructions sent to them to reproduce the rendering on a new render target.

Implementations

impl Canvas

pub fn stream(&self) -> impl Stream<Item = Draw> + Send

Creates a stream for reading the instructions from this canvas

pub fn get_drawing(&self) -> Vec<Draw>

Retrieves the list of drawing actions in this canvas
