public Variant? gvariant_deserialize (Node json_node, string? signature) throws Error
Converts a JSON data structure to a `GVariant`.
If `signature` is not `NULL`, it will be used to resolve ambiguous data types.
If no error occurs, the resulting `GVariant` is guaranteed to conform to `signature`.
If `signature` is not `NULL` but does not represent a valid `GVariant` type string, `NULL` is returned and the `error` is set to `G_IO_ERROR_INVALID_ARGUMENT`.
If a `signature` is provided but the JSON structure cannot be mapped to it, `NULL` is returned and the `error` is set to `G_IO_ERROR_INVALID_DATA`.
If `signature` is `NULL`, the conversion is done based strictly on the types in the JSON nodes.
The returned variant has a floating reference that will need to be sunk by the caller code.
