- When casting a value to an enum, there's no checking that the value
actually is a valid enum value. Don't think I ever found a solution on
how to check whether the value after casting is a valid enum value, it
hasn't been a pressing issue.
Typically, one uses std.conv.to to safely convert one value into another.
Cast should be avoided unless absolutely necessary.
I just tested it, it works on enum *strings*, but not enum *values*
For example:
import std.conv;
enum X {
i, j, k
}
void main()
{
X x = to!X("i"); // works!
x = to!X(1); // fails!
}
I think to should be able to do this, but I'm not a good enough guru with
templates and compile-time type info to know if it's possible. Anyone
know if this is possible? If so, I think it should be added.
