## What it is
Rattles is a minimal, dependency-free terminal spinner/throbber library for Rust with built-in presets (arrows, ascii, braille, emoji) and a macro for custom keyframes. It supports no_std environments and integrates with ratatui-based TUIs.

## Use cases
- show a loading spinner in a rust cli
- add a throbber animation to a ratatui tui app
- render progress indicators in a no_std embedded terminal
- create custom ascii spinner keyframes
- add animated indicators to terminal output

## When to choose
- you need a tiny, dependency-free spinner library in Rust
- you want no_std support or custom frame timing control
- you're building a ratatui TUI and need throbber frames

## When to avoid
- you need full-featured progress bars with percentages and ETA
- you want a library that manages its own rendering thread and output

## Facets
- artifact type: library
- maturity: active
- function: animation, terminal-ui, cli
- domain: developer-tools, cross-platform
- platform: rust, cli, cross-platform
- tags: spinner, throbber, tui, ratatui, no-std, dependency-free, command-line
