pub fn sweep(
id: impl Into<ElementId>,
theme: &Theme,
color: Hsla,
cx: &App,
) -> Option<AnyElement>Expand description
A band travelling across whatever it is placed in, for work of known extent.
Returns an absolutely positioned overlay, so the caller adds it as a child
of a relative().overflow_hidden() element and nothing it already draws
moves. It paints in color, which callers set to the accent or to the
track they are sweeping over.
