README

Psalm doesn't detect situations when we try to create backed enums using from method with a wrong literal

For example:

enum StringEnum: string { case ONE = 'one'; /**  * @param 'two' $value  */ public static function createSelf(string $value): void { /**  * Psalm won't complain  */ self::from($value); } }

Might be useful if you generate OAS enums as phpdoc union literals and want to know about type problems before running your code

Installation

Psalm documentation

or by manually adding to your psalm.xml
