Animated spinner for indeterminate loading states.

Import

const Spinner = tui.Spinner;

Animation

You can update the spinner based on the render context time.

pub fn render(self: *MyComp, ctx: *tui.RenderContext) void {
    // Return value indicates if redraw is needed (frames updated)
    _ = self.spinner.update(@intCast(ctx.time_ns));

    self.spinner.render(ctx);
}
