On: You can’t “turn off the borrow checker” in Rust

[saghm]

I might be in the minority here (and I don't do game development, which is the topic of this thread), but I tend to start by using `vec.get(i)` (which returns an option) and then only switch to the index notation if I end up checking the length immediately beforehand and want to do an early return or something to avoid extra indentation in the code where I use the accessed element.

I think modern C++ compilers are smart enough to eliminate the bounds check if they can prove that it never fails.

Yup, Rust will too.

I mainly do it this way to reduce the chance of my code panicking, not specifically for any performance reasons.
