Elegant and performant recursion in Rust

Elegant and performant recursion in Rust.
This is a post about writing elegant and performant recursive algorithms in Rust. It makes heavy use of a pattern from Haskell called recursion schemes, but you don’t need to know anything about that; it’s just an implementation detail. Instead, as motivation, I have benchmarks showing a 14-34% improvement over the typical boxed pointer representation of recursive data structures in Rust.
