Well, a lot of C/Odin/Zig people will point out that Rust's stdlib encourages heap allocations. For actually best performance you typically want to store your data in some data-oriented data model, avoid allocations and so on, which is not exactly against idiomatic Rust, but more than just a typical straighforward Rust just throwing allocations around.
