The code was pared down from a lot of string mixin code generation. I
nest the structs because I want a nested enums. I don't want have to
have eState and eStateType but eState and eState.Type.
Having the ability to nest enums would solve my problem.
Regardless, I can almost achieve the effect with nested structs but not
quite.
In the code, I cannot assign to the struct for some reason even with
alias this on iB, which should make State act like the int Value.
i.e.,
b.State.Value = Enums.State.A;
works but
b.State = Enums.State.A;
doesn't
It maybe some stupid error on my part but I can't keep my eyes open
enough to figure it out...
For that assignment to work, the left-hand side must be assignable.
However, the property function State() returns Enums.eState by-value.
The following has the same issue:
struct S
{
int i_;
@property int i() {
return i_;
}
alias i this;
}
void main()
{
auto s = S();
s = 42;
assert(s.i == 42);
}
Error: cannot implicitly convert expression (42) of type int to S
To compile, i() must return an lvalue:
@property ref int i() {
Ali
