Available types
"Atomic" types are any which can't contain any other types. Only atomic types may be used as dictionary keys.
Every type has an associated type code; a textual representation of the type, useful for debugging.
Variants may contain any other built-in D-Bus value. Besides
representing native VARIANT values, they allow type-safe storage and
deconstruction of heterogeneous collections.
Every variant is strongly-typed; that is, the type of its contained value is known at all times. This function retrieves that type, so that the correct cast can be used to retrieve the value.
This is the type contained within the array, not the type of the array itself.
