The post is called "Rust for functional programmers" and contains side-by-side comparisons with both OCaml and Haskell. http://science.raphael.poss.name/rust-for-functional-program... you might be confusing it with the other post "Haskell for OCaml programmers"?

It is a bit outdated but as far as I can see not inaccurate yet. I only plan to update it when HKTs make it to Rust.
