While Rust has a concept of interface, it differs from other programming languages in that it does not use the interface keyword to specify the behavior of classes and functions. Instead, Rust’s closest abstraction pattern is trait. Although these concepts have many differences, they both address the problem of having multiple possible implementations.
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.
Declaration
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 interface to share this common information.
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.
