How can I use this code or something similar to dynamically
construct a tuple containing types of fields marked as
@Cloneable?
import std.traits, std.typetuple;
template CloneableTypes(S) {
template IsCloneable(string M) {
enum IsCloneable = staticIndexOf!(Cloneable,
__traits(getAttributes, __traits(getMember, S, M))) = 0;
}
template FieldType(string M) {
alias FieldType = typeof(__traits(getMember, S, M));
}
alias CloneableTypes = staticMap!(FieldType,
Filter!(IsCloneable, __traits(allMembers, S)));
}
Then CloneableTypes!Foo is a TypeTuple (int, string).
