Function canvas 

pub fn canvas(paint: impl Fn(&mut PaintCx<'_>, Size) + 'static) -> Canvas

Creates a new Canvas view that can be used for custom painting

A Canvas provides a low-level interface for custom drawing operations. The supplied paint function will be called whenever the view needs to be rendered, and any signals accessed within the paint function will automatically trigger repaints when they change.

Example

use floem::prelude::*;
use palette::css;
use peniko::kurbo::Rect;
canvas(move |cx, size| {
    cx.fill(
        &Rect::ZERO
            .with_size(size)
            .to_rounded_rect(8.),
        css::PURPLE,
        0.,
    );
})
.style(|s| s.size(100, 300));
