> Indexing into a vector unwraps

That's what it's supposed to do, RTFM.

Use .get() for safe access.




Er, yes I know, I use rust every day as a primary language. I was just giving an example, not claiming it wasn’t documented.


Then what is the issue if you know both the “fast-but-panicking” and “slow-but-Option-ing” versions?


First of all, neither is faster than the other.

Second, I never claimed it was an issue or a bad thing at any point. Someone asked for examples of libraries that panic, and I gave an example.

I must be missing something because it makes no sense to me that people seem to be responding defensively and claiming that I either don’t understand the Rust docs or am pointing out problems in Rust.
