Hi everybody,
I would like to extract key and value type from AA.
I found this answer on forum :
template AATypes(T)
{
// todo: static assert if T is no AA type here
alias ArrayElementType!(typeof(T.keys)) key;
alias ArrayElementType!(typeof(T.values)) value;
}
But compiler failed,I thi

So how can I get types without instance ?
Thanks for help.

You can also do it with built-in syntax:
template AATypes(AA : K[V], K, V)

I see, maybe .KeyType and .ValueType should be integrated in AA.
Or like C++ with map, make a ValueType(::value_type) field wich contain
a pair of type.
Currently, they are templates in std.traits:
