lionel-rowe	836134202e	feat(options2): better tests for layered_option ... The existing test can be solved with the following: ```rs while let Some(integer) = optional_integers.pop() { assert_eq!(integer.unwrap(), range); ``` Similarly with `expect(...)`, `unwrap_or(0)`, `unwrap_or_default()`, etc. However, none of these solutions use the learning point of stacking `Option<T>`s. The updated test can _only_ be solved by stacking `Option<T>`s: ```rs while let Some(Some(integer)) = optional_integers.pop() { assert_eq!(integer, cursor); ``` With the updated test, using `unwrap` or `expect` will panic when it hits the `None` value, and using `unwrap_or` or `unwrap_or_default` will cause the final `assert_eq!(cursor, 0)` to panic.	2023-04-21 06:05:25 +01:00
