About:
Rune is an embeddable dynamic programming language designed to run within Rust applications. It provides a scripting interface that allows developers to add dynamic logic and user-defined scripting capabilities to their Rust programs without sacrificing performance or safety.

Key Features:

Native Rust integration for seamless embedding
Dynamic typing with a syntax inspired by Rust
Support for async/await and generators
Rich macro system for metaprogramming
Zero required dependencies

Use Cases:

Adding user-defined scripting to Rust applications
Creating extensible plugins for Rust software
Rapid prototyping of logic within a Rust environment
Configuration and logic separation for complex systems

Alternatives:

Rhai – Rhai is a simpler, single-file scripting language, while Rune offers a more feature-rich language with async support and syntax closer to Rust.
Lua (via mlua) – Lua is a widely used, battle-tested embedded language, but Rune offers tighter integration with Rust's type system and ownership model.
