fn main() { const s: &str = "⊗ symbol"; const n: usize = s.chars().count(); println!("{}", n); } why i can't compile this. even though s is const. so the n of char is const and so count is const and know at compile time.

Why can't I call .chars().count() on a const &str?

For future reference: that is this thread from 4 days ago with about the same question.
