Caution

**ABANDONED: The functionalities of this library have been integrated into the Laravel core due to changes in Laravel [v10.20.0](https://github.com/laravel/framework/releases/tag/v10.20.0). From now on, the `Illuminate\Database\UniqueConstraintViolationException` exception class will be thrown when there is a unique constraint violation, so there is no need to use this library for judgment. Simply checking with `catch` or `instanceof` should be sufficient. Although the internal judgment logic is strictly different in some parts, it should be replaceable without any problems in most cases.**

Detect **primary/unique key or constraint violation** errors from `PDOException`.
