**Summary** [Option::is_some_and](https://doc.rust-lang.org/stable/std/option/enum.Option.html#method.is_some_and) and [Result::is_ok_and](https://doc.rust-lang.org/std/result/enum.Result.html#method.is_ok_and) are new methods is rust 1.70. I find them way more readable than `.map_or(false, ...)`. The changes are `s/.map_or(false,/.is_some_and(/g`, then manually switching to `is_ok_and` where the value is a Result rather than an Option. **Test Plan** n/a^
