We've seen how to use if-else and else if to make decisions in our code. However, when you have a long chain of else if statements, it can become clumsy. For more complex conditional logic, Rust has a powerful control flow construct called match. A match expression allows you to compare a value against a series of patterns and then execute code based on which pattern matches.
In the previous article, we learned the basics of match expressions. Now, we're going to explore some of the more advanced patterns that make match one of Rust's most powerful features. These patterns allow you to write even more expressive and concise conditional code.
We've seen the match expression a few times already, especially when working with enums like Option and Result. In this article, we're going to take a deeper dive into what makes match so powerful: pattern matching.
We've seen how powerful the match expression is for pattern matching. However, sometimes a match can be a bit verbose, especially when you only care about one of the possible cases. For these situations, Rust provides a convenient shorthand: if let.
