Bench Ruby FFI Example

This repository is an educational resource for examining the cost of alternative ways in implementing type safety across Ruby & Rust FFI and what performance gains you may have when implementing extra type guards is not necessary.

Ruby 2.4.2 & Rust 1.23.0-nightly

  Basename Comparison:
       Ruby's C impl:   661812.2 i/s
        through ruru:   652184.5 i/s - same-ish: difference falls within error
     with pure input:   492597.7 i/s - 1.34x  slower
      rust nil guard:   481088.2 i/s - 1.38x  slower
      ruby nil guard:   439570.8 i/s - 1.51x  slower
    with type safety:   375606.3 i/s - 1.76x  slower

Plans

Implementations for Helix, FFI::AutoPointer, FFI::ManagedStruct, and Fiddle are planned. Continuous integration through CodeShip is welcome as well.

Contributing

There is much that can be learned about performance improvements when it comes to integrating Rust and Ruby. You're welcome to contribute to theis repository through issues and PRs. Welcome additions include style & organization of code for clarity, alternative implementations or new libraries to integrate. Other ideas are welcome as issues.
