The big difference between Rust and OCaml is that a company the size of Jane Street can influence OCaml development, while it takes one the size of Amazon (according to the recent accusations) to do the same with Rust. I think OCaml has one of those "ancient" communities that seem to value independence more than consensus. Rust is very hard to build without cargo, OCaml works fine with make or dune. I'm not sure if focusing on independence is the right tradeoff for most companies, but I can see some cases where it might be.

IDE support is getting there with OCaml. In VSCode, it's not as good as TypeScript but it's usable.

There are a few libraries that you can use. Serde also tends to make the already long compilation time blow up.
