bd-validation-rule

What problem does it solve?

Enforces the addition of new, pure validation rules to BetterData by implementing the Rule interface and decorating data objects with #[Rule] attributes, ensuring rules remain predictable and composable.

Core Features & Use Cases

• Pure, attribute-based rules that implement the Rule contract.
• Automatic null handling: rules skip null values unless paired with #[Required].
• Use Case: introduce a new rule to enforce a specific data format on a DTO field.

Quick Start

Create a new PHP class implementing BetterData\Validation\Rule, add a #[Rule] attribute, and wire it into the validation system.
