In our journey so far, we&rsquo;ve learned how to define custom data structures using <code>struct</code>s and <code>enum</code>s. These are fantastic for organizing data, but what about behavior? How do we define a set of actions that different types can share, or ensure that a function can operate on <em>any</em> type that possesses a certain capability?</p> <p>This is where <strong>traits</strong> come into play! Think of traits as Rust&rsquo;s powerful way to define shared behavior. They are similar to interfaces in other languages (like Java or Go) or typeclasses in Haskell. Traits allow you to tell the Rust compiler: &ldquo;Any type that implements <em>this</em> trait promises to have <em>these</em> methods.&rdquo; This chapter will demystify traits, showing you how they enable polymorphism, promote code reuse, and are fundamental to writing idiomatic and extensible Rust applications.</p>
