@get
Description:
Deconstructs a Variant instance.
Think of this function as an analogue to scanf.
The arguments that are expected by this function are entirely determined by format_string. format_string also
restricts the permissible types of this. It is an error to give a value with an incompatible type. See the
section on [GVariant format strings](gvariant-format-strings.html). Please note that the syntax of the format string is very likely to be
extended in the future.
format_string determines the C types that are used for unpacking the values and also determines if the values are copied or
borrowed, see the section on [`GVariant` format strings](gvariant-format-strings.html#pointers).
Parameters:
| this |
a Variant instance |
| ... |
arguments, as per |
| format_string |
a Variant format string |
