<h1>Understanding Rust's Ownership System</h1>
<p><em>Published on October 15, 2025</em></p>
<p>Rust's ownership system is one of its most unique features...</p>
<h2>What is Ownership?</h2>
<p>Ownership is a set of rules that govern how a Rust program manages memory.</p>
<h3>The Three Rules of Ownership</h3>
<ol>
<li>Each value in Rust has a variable that's called its owner.</li>
<li>There can only be one owner at a time.</li>
<li>When the owner goes out of scope, the value will be dropped.</li>
</ol>
<h2>Code Example</h2>
<pre><code class="language-rust">fn main() {
let s1 = String::from("hello");
let s2 = s1; // s1 is moved to s2
println!("{}", s2); // This works
// println!("{}", s1); // This would fail!
}</code></pre>
<blockquote>
<p><strong>Tip:</strong> Think of ownership like a book - only one person can own it at a time!</p>
