They are used whenever a specific field of the base type is declared as the discriminator ('type' is -then no longer generated). The discriminator can be a string field or a -predefined enum field. If it is a string field, a hidden enum type will be -generated as "[UNION_NAME]Kind". If it is an enum field, a compile time check -will be done to verify the correctness.
