hunt-validation

hunt-validation is a data validation library for the D programming language, built on top of the Hunt framework. It provides a robust and type-safe way to validate data structures, ensuring data integrity and consistency in D applications.

Key Features

• Annotation-based validation — Uses D's annotation system to define validation rules directly on struct and class fields.
• Built-in validators — Includes common validators for email, URL, length, range, and custom regex patterns.
• Custom validation rules — Allows developers to define their own validation logic through custom validator classes.
• Nested object validation — Supports validation of complex nested objects and collections.
• Error message customization — Provides flexible error message handling and internationalization support.

Philosophy

The library emphasizes type safety and compile-time checks where possible, leveraging D's powerful metaprogramming capabilities to create a validation system that is both expressive and efficient.
