I'm trying to set fields of object from JSON with traits library. How i

foreach(field; FieldNameTuple!T){
alias member = Alias!(__traits(getMember, T, field));
static if (__traits(hasMember, member, "fromJSON")){
member.fromJSON(j[field]);
} else {
member = j[field];
I'm pretty sure this won't work. You need to use "this.tupleof[index] =
value" to set a value. You can iterate all fields using "T.tupleof" and
then get the name of a field using "__traits(identifier,
T.tupleof[index]);". Or you can use a string mixin.
