  "textContent": "It's maybe less a footgun in Rust due to strong integer typing; you know when it's a `usize` vs a `isize`. On the other hand, you may want a `isize` but forget to cast and have `usize` overflow auto-wrapping, so you enter another category of error prone. Anyway, I agree with you.\n\nIt's a bit annoying that sometime, you need `[..s.len() - 1]` but you already have a mutable reference on `s` so you need to extract `s.len()` in a variable, but that's rare enough to make with it.",
