Enums in Rust

In Rust, an enum is a type that represents a value that can be one of several possible variants. Enum is short for enumeration, which means a list of distinct values.

In this chapter, we're going to understand enums in Rust, how to define them and how to use them in our programs, enums just like structs have implementations and methods as well, we're going to see how to implement methods on enums.

We'll also explore the advanced pattern matching system in Rust, which is a powerful feature that allows us to match on different enum variants and extract values in various ways.

We'll also explore some useful enums in the Rust standard library, such as Option , which is used to handle optional values since in Rust there is no such thing as a null or nil value, and Result , which is used to handle errors in Rust.

Let's get started!
