sealed.deprecatedTrait

Code example

<?php declare(strict_types = 1);

/** @deprecated Use NewTrait instead */
trait DeprecatedTrait {}

/**
 * @phpstan-sealed DeprecatedTrait
 */
class Foo
{
}

Why is it reported?

This error is reported by the phpstan-deprecation-rules extension.

The @phpstan-sealed PHPDoc tag references a trait that has been marked as @deprecated. Deprecated traits are planned for removal in a future version, and sealed constraints should not depend on them.

How to fix it

Replace the deprecated trait reference with its non-deprecated replacement:

 /**
- * @phpstan-sealed DeprecatedTrait
+ * @phpstan-sealed NewTrait
  */
 class Foo
 {
 }
