Add missing descriptors for SmallFloatType and EnumType

[janedbal]

• Implement an EnumType for MySQL/MariaDB doctrine/dbal#6536 (since dbal 4.2)
• Add SmallFloat type doctrine/dbal#6471 (since dbal 4.1)
• Resolves Doctrine DBAL 4.2 ships an Types::ENUM which should be preferred over implementing custom types for ENUM fields. #619

At first, I tried adding new doctrine versions to composer.json, but it would require bigger effort to adjust this repo to support those everywhere, so I just referenced those not-yet-existing classes.

No inheritance please

Are you sure? I believe SmallFloatType IS FloatType in terms of type descriptor.

Am I wrong or without this type the data is considered as mixed ?

Now with this, it will report error foo be 'A'|'B' but is string on level 8 because the values option is not considered in the following code

#[ORM\Column(name: 'foo', type: Types::ENUM, options: ['values' => ['A', 'B'])]

You are correct.

It is pretty painful to test new doctrine here (due to all the compatibility hacks). But added.

The enum type will introduce new false-positive.

Before

/**
   * @Column(type="enum", options={"values"={"a", "b", "c"}})
   * @var 'a'|'b'|'c'
   *
   public $enum;

Was reported level 9 (mixed is not 'a'|'b'|'c')
and now will be reported on a lower level (string is not 'a'|'b'|'c')

Would it be possible to read the options ?

[janedbal]

Would it be possible to read the options ?

Yes, implemented.

Yes, implemented.

Great.

Could add a test for the EntityColumnRule too

phpstan-doctrine/tests/Rules/Doctrine/ORM/EntityColumnRuleTest.php

Line 35 in a1a9efb

class EntityColumnRuleTest extends RuleTestCase

(I assume we just need to add an enum field in the BrokenEntity https://github.com/phpstan/phpstan-doctrine/blob/a1a9efb64708580a9d8b0d150340f7777d2b8aa0/tests/Rules/Doctrine/ORM/data/MyBrokenEntity.php)

I assume that

/**
   * @Column(type="enum", options={"values"={"a", "b", "c"}})
   * @var 'a'|'b'|'c'
   *
   public $enum;

shouldn't be reported but

/**
   * @Column(type="enum", options={"values"={"a", "b", "c"}})
   * @var string
   *
   public $enumWithUnprecisedPHPDoc;

should be reported
