pub fn cover<M>(url: impl Into<String>, fallback: Node<M>) -> Node<M>Expand description
A picture a program hands over at runtime, by URL: a track’s cover art. file:// and
https:// URLs load; the host fetches, crops it square and rounds it, off the UI thread, and
keeps the few latest. Drawn at icon size, or big with Node::large. Until it’s there, or if
it can’t be loaded, fallback shows in its place. A tone only dims it.
