rattles-terminal-spinners — Claude Code skill for Rust spinners

What rattles-terminal-spinners does

The skill walks through how rattles works and how to wire it into a project. A spinner here is a Rattler: a set of frames plus an interval. It holds no state, so you can build one inside a render loop, and that costs almost nothing.

Presets are grouped by category — arrows, ASCII, braille, emoji — and the rattle! macro defines custom keyframes at compile time. For environments without the standard library there is TickedRattler, which keeps state and advances on each tick() call. Stateless alternatives exist too: pick a frame by index, or pass an elapsed duration from your own timer. A separate section covers ratatui, where a Rattler is passed by reference and needs no Arc<Mutex<>> wrapper.

Add the library with cargo add rattles, or with --no-default-features for no_std. If the spinner freezes on its first frame, check that you flush stdout and overwrite the line with \r rather than \n.
