Agreed, rust is SUPER not fun IMHO but I use it a lot via FFI for things I wouldn't do in Elixir which I prefer to write/read. The broad array of well built tools on cargo is just so hard to compete with, and cargo as a tool beats any language tooling for any language with similar breadth. The JVM has every tool imaginable but I'd rather built it myself than tangle with JVM tooling.
