Pattern matching is one of Rust’s most powerful features. It lets you compare values against structures, safely extract data, and execute different logic depending on what you find — all in a clean, expressive way.
Unlike a simple <code>if/else</code>, Rust guarantees exhaustiveness at compile time. If you forget a case, your code won’t compile.
In this guide, I cover:
<ul>
<li>Destructuring with <code>let</code> (tuples, structs, enums)</li>
<li>The <code>@</code> binding operator</li>
<li>Irrefutable vs. refutable patterns</li>
<li><code>let else</code>, <code>if let</code>, <code>while let</code>, and let chains</li>
<li><code>match</code> as an expression (and exhaustiveness)</li>
<li>Or-patterns (<code>|</code>) and wildcards (<code>_</code>)</li>
<li>Range patterns (<code>..=</code>) and value binding with ranges</li>
<li>Slice and array patterns</li>
<li>Pattern guards (<code>if</code> in match arms)</li>
<li>Nested enum matching</li>
<li>Matching <code>Option&lt;T&gt;</code> and <code>Result&lt;T, E&gt;</code></li>
</ul>

A comprehensive guide to pattern matching in Rust, covering destructuring with `let` for tuples, structs, and enums, the `@` binding operator, irrefutable vs. refutable patterns, `let else`, `if let`, `while let`, and let chains, `match` as an expression with exhaustiveness guarantees, or-patterns, wildcards, range patterns, slice and array patterns, pattern guards, nested enum matching, and working with `Option<T>` and `Result<T, E>`.
