How to assign a value to a custom Struct?

[sunmerx]

NeoLua Version:1.3.14

Example to reproduce:

item = plcns.WriteDataItem(){
    DataArea = plcns.DataAreaType.DB;
    DBNumber=660;
    StartAddress=100;
    ValueType=plcns.DataType.INT;
};

I'm trying to embed a script into a program so that the logic depends on the script. Initialize a custom body in a script and cannot assign values to its members.

Can you show the signature of plcns and WriteDataItem?
