value_can_union

function value_can_union(value1:GObject.Value, value2:GObject.Value):Boolean {
    // Gjs wrapper for gst_value_can_union()
}

Determines if value1 and value2 can be non-trivially unioned. Any two values can be trivially unioned by adding both of them to a GstValueList. However, certain types have the possibility to be unioned in a simpler way. For example, an integer range and an integer can be unioned if the integer is a subset of the integer range. If there is the possibility that two values can be unioned, this function returns TRUE.
