rustygem | An example of a Ruby gem written in Rust

rustygem is a Ruby library. rustygem has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

This is a boilerplate example of Ruby gem with native extension written in Rust. It will compile on target system using gem's native mechanism, but you have to have Rust and Cargo installed on the target system. It uses Ruby Fiddle module to pass data between Ruby and Rust. For simplicity it uses JSON to pass complex data structures between Ruby and Rust. You might want to use Ruby ffi to convert real types between Ruby and Rust, however, this requires more effort and possibly leads to memory management errors. But JSON is dead simple and robust. Also, take a look at Helix project, which creates nice boilerplate-free API to communicate with Rust in Ruby.
