So, a first pass of https://doc.rust-lang.org/stable/book/ suggests Rust is focused on safety; speed; and concurrency but then it doesn’t appear to suggest what Rust’s limitations might be, relative to other languages.

For a noob, could someone suggest whether Rust is necessarily at a disadvantage in some areas?

If you were looking at an ideal polyglot stack, what languages would be the best for what tasks… or is it always very subjective and relative to the application and more often about the skill set of the devs involved?
