Rust Programming Master Class from Beginner to Expert - Option Enum

This tutorial covers the option enum in Rust, explaining its importance in handling optional values and error management. The option enum has two variants: none, indicating absence of a value, and some, indicating presence of a value. The tutorial provides examples of using option enum with different data types and demonstrates how to use it in functions. It also highlights the use of match statements to handle different variants and discusses the scope of variables within match blocks. The tutorial concludes with a brief mention of the result enum, which will be covered in a subsequent tutorial.
