The 'Option' Enum represents either a value (Some) or no value at all (None). It is common to see this in Rust with many methods and functions returning this particular type.

It's useful because it forces us to deal with unexpected situations such as when the expected return value of a function does not actually provide a value - because it doesn't exist or can't be found.

In this video we look at a common example of the Option Enum in use and we also define our own function that returns an Option type to truly understand how it works.
