Serializer

Default serializer for ObjectId.

When serializing to BSON

ObjectId instances are encoded using MongoDB's native BsonType.ObjectId BSON type.

Supported drivers:

• The official :bson-kotlinx serialization library.

• The KtMongo Multiplatform driver.

When serializing to other formats

When serializing to other formats, like JSON, ObjectId instances are represented as 24-characters hex strings.
