Charlie Explains Rust Iterators

Option<T> ok_or ok Result<T, _> is_some unwrap Some unwrap Ok is_ok bool iter next last find for_each fold all any Iterator<T>

The joke is that Rust’s Option, Result, and iterator APIs look absurdly complicated when mapped out, making this a reaction to confusing programming concepts or overthinking code.
