Rhai

Rhai is a lightweight, embedded scripting language and evaluation engine designed specifically for integration into Rust applications, offering a safe and flexible way to add dynamic behavior without sacrificing performance or security. It features a syntax that blends familiarity from JavaScript and Rust, making it approachable for developers while maintaining expressive power through dynamic typing and simple constructs. Rhai is optimized for embedding, allowing developers to expose native Rust functions, types, and data structures directly to scripts, enabling seamless interoperability between compiled and interpreted code. The engine is designed with minimal reliance on unsafe code, prioritizing safety while still delivering efficient execution performance suitable for real-time applications. It supports a wide range of data types, including arrays, maps, and Unicode strings, as well as custom types defined in Rust, making it versatile for scripting complex logic.
