function FieldsInterface::getVariant

Returns the variant

The variant number describes the layout of the UUID. The variant number has the following meaning:

  • 0 - Reserved for NCS backward compatibility
  • 2 - The RFC 4122 variant
  • 6 - Reserved, Microsoft Corporation backward compatibility
  • 7 - Reserved for future definition

For RFC 4122 variant UUIDs, this value should always be the integer `2`.
