USING RUST IN NON-RUST SERVERS TO IMPROVE PERFORMANCE

Summary from the TLDR newsletter

This article discusses different strategies for incrementally adding Rust into a searcher written in another language. Developers may want to do this if they identify functions not meeting their performance requirements because they're being bottlenecked by the CPU and the usual techniques of memoizing the function or improving its algorithm aren't feasible or effective. Sometimes, it's worth investigating swapping out the function implementation for something written in a more CPU-efficient language - like Rust.
