Rattles

Dependency-free terminal spinner library for Rust with presets and custom keyframes

Aboutgithub.com

Rattles is a minimal terminal spinner library for Rust. It has no dependencies and makes no assumptions about where the output goes. Presets cover common spinners, and a macro defines custom keyframes with a row count and an interval in milliseconds. The library also works without the standard library.

Install

cargo add rattles

For an agent

Use it for loading states in a Rust command-line tool. It only produces frames, so your code decides how and where to print them.

Why it is here. It brings loader design to terminal tools without extra dependencies.
