Symfony Casters for MongoDB Extension classes

[GromNaN]

Working on the profiler, I found that most ext-mongodb classes are not correctly dumped by symfony/var-dumper. The specific dumpers could be integrated to Symfony directly, but we can start implementing them in this project for compatibility with Symfony 6.4 LTS.

Example for WriteConcern, it should show the value.

See existing casters: https://github.com/symfony/symfony/tree/6.4/src/Symfony/Component/VarDumper/Caster

Driver

• Cursor
• ReadConcern
• ReadPreference
• WriteConcern

BSON

• Document
• PackedArray
• Iterator
• Binary
• Decimal128
• Javascript
• MaxKey
• MinKey
• ObjectId
• Regex
• Timestamp
• UTCDateTime

dump(new \MongoDB\Driver\ReadPreference(\MongoDB\Driver\ReadPreference::RP_PRIMARY));
dump(new \MongoDB\Driver\WriteConcern(\MongoDB\Driver\WriteConcern::MAJORITY, 1000));
dump(new \MongoDB\Driver\ReadConcern(\MongoDB\Driver\ReadConcern::LOCAL));
dump(new \MongoDB\Driver\Command(['foo' => 'bar']));
dump(new \MongoDB\Driver\Query(['foo' => 'bar']));
dump(new \MongoDB\Driver\BulkWrite());
dump(new \MongoDB\BSON\UTCDateTime(1));
dump(new \MongoDB\BSON\Int64(1));
dump(new \MongoDB\BSON\Regex('foo', 'i'));
dump(\MongoDB\BSON\Document::fromPHP(['foo' => 'bar']));
dump(\MongoDB\BSON\PackedArray::fromPHP(['foo', 'bar']));
dump(new \MongoDB\BSON\Timestamp(1, 2));
dump(new \MongoDB\BSON\UTCDateTime());
dump(new \MongoDB\BSON\Binary('foo', \MongoDB\BSON\Binary::TYPE_GENERIC));
dump(new \MongoDB\BSON\Decimal128('1.2'));
dump(new \MongoDB\BSON\Javascript('function (a) { return a; }', ['a' => 'foo']));
dump(new \MongoDB\BSON\MaxKey());
dump(new \MongoDB\BSON\MinKey());
dump(new \MongoDB\BSON\ObjectId());

Yes implementing them here as internal and contributing it back to Symfony 7.1 🤓🖖
