ruru

Allows releasing the GVL (Global VM Lock) to run Rust code in parallel with Ruby threads, enabling significant performance gains for CPU-bound tasks, as shown in the heavy computation example.

Provides verified object conversions between Ruby and Rust types with proper error handling, reducing runtime errors and improving safety, demonstrated in the safe conversions section.

Enables replacing individual Ruby methods or classes with Rust implementations without changing the public API, facilitating gradual optimization without breaking existing code.

Offers a Rust-based DSL for defining Ruby classes, methods, and constants, making integration intuitive and similar to writing Ruby code, as seen in the class definition examples.
