Data validation is a cornerstone of robust applications. It ensures that the data your application processes conforms to expected formats and business rules, preventing errors and maintaining data integrity.
If you're familiar with Django REST Framework (DRF) in Python, you'll appreciate its powerful and declarative validator system.
In this article, we'll explore how to build a type-safe and flexible validator system in Rust, taking cues from DRF's elegant design. We'll start with a basic structure and progressively enhance it to create a more practical and feature-rich solution.

Let's begin by opening a base Rust structure for our validator system:
