Valgo: An Expressive Validator Library — Type-safe and extensible validator library that supports localization and is built upon generics. “Valgo differs from other validation libraries in that the rules are written in functions and not in struct tags. This allows greater flexibility and freedom when it comes to where and how data is validated.”
