Rust for Rubyists
summary
Claim is that Rubyists should drop down to Rust for performance not fear, with concrete examples and tools: Rust uses ahead of time compilation and LLVM, produces small assembly after optimization, and applies monomorphization to turn generics into specialized fast calls. Uploader shows how a Rust reimplementation of ActiveSupport splitting outperforms the C gem, explains Box memory ownership eliminating manual free, and shows generated assembly shrinking to nothing when code is unused, so the thing built actually works.
