Examples sample code invoking the structSetMetadata function

Add metadata to a struct and serialze to a json.
It is changing the keyname and convert a string ("20") to a number.

testStruct.testdata = "example";
testStruct.testdata2 = "20";
metadata = {
    testdata: {type: "string", name: "td1" },
    testdata2: {type: "numeric", name: "td2" }
};
StructSetMetaData(testStruct,metadata);
writeoutput(SerializeJSON(testStruct));

Expected Result: {"td1":"example", "td2":20.0}
