Listener

Single listener; parameter is interface with single method

struct Listener(T1)
struct Listener (
T1
) if (
is(T1 == interface) &&
__traits(allMembers, T1).length == 1
) {
alias return_t = ReturnType!(__traits(getMember, T1, __traits(allMembers, T1)[0]));
alias params_t = ParameterTypeTuple!(__traits(getMember, T1, __traits(allMembers, T1)[0]));
alias slot_t = return_t delegate(params_t);
bool assigned();
void opAssign(slot_t listenerDelegate);
void opAssign(T1 listenerObject);
return_t opCall(params_t params);
slot_t get();
}
