The Algorithm (The It)The original paper uses an implementation of a loop recognition algorithm as a benchmark. Idiomatic RustIf the goal is to write an idiomatic implementation of the algorithm in Rust, the place to start is Safe Rust. push ( from ) ; } }Implementing in Safe RustHitting each of those bullet points really didn't describe how the Safe Rust implementation differs from the C++ or Unsafe Rust implementation. I originally wanted to try to re-implement the original C++ using Modern C++ for comparison as well as a version similar in style to the Safe Rust version. When moving to Unsafe Rust, the near identical implementation of the algorithm as the untuned C++ not only beat the C++ but the Safe Rust as well.
