Rust Trait: A Powerful Alternative To TypeScript Interface
<p>While Rust has a concept of interface, it differs from other programming languages in that it does not use the <code>interface</code> keyword to specify the behavior of classes and functions. Instead, Rust’s closest abstraction pattern is <code>trait</code>. Although these concepts have many differences, they both address the problem of having multiple possible implementations.</p>
<p>In this blog post, I will compare a TypeScript code snippet with its potential Rust equivalent to demonstrate how to achieve a simple flexible and composable code.</p>
<h1><strong>Declaration</strong></h1>
<p>Let’s imagine a project that involves saving and listing documents and images in a database. Since both types of files are stored in the same storage and share common characteristics, we could use an <code>interface</code> to share this common information.</p>
<p>Using an interface would allow us to define a set of properties and methods that are common, making it easier to write code that works with either type of file.</p>
