is_some

is_none

Options can have a Some value, with an inner value, or a None value, without an inner value.
|
||||
There's multiple ways to get at the inner value, you can use unwrap, or pattern match. Unwrapping
|
||||
is the easiest, but how do you do it safely so that it doesn't panic in your face later?"""
