Module spinner 

Available on crate feature spinner only.

An indeterminate loading spinner.

The spinner has no clock of its own. The app keeps a phase in its state, advances it with advance on each frame while loading (for example from iced::window::frames()), and stops subscribing when it is done.

The track and the arc are small SVG images drawn through iced’s image path, which behaves the same on every backend. The arc comes from a fixed set of FRAMES pre-rotated images, so spinners at the same phase share one cached image.
