I have seen a code a while ago, but even by looking at
documentation, I couldn't have found anything about it.
Let's say I have defined an enum;
enum Status: ubyte{
Busy = 1,
Active = 2
}
and received a ubyte value from user.
ubyte userValue;
I want to switch over userValue, but that should depend on Status.
switch( userValue ){
...
}
What I mean is that compiler should enforce values of enum
"Status" to be declared in switch as it would be done with "final
switch", but as you can guess, user might enter a value that is
not defined by Status. Thus, I should be able to enter the case
"default" as well.
I remember it something like switch( userValue ) with( Status
){...}, but not sure about it. Maybe it was D1 code. Is there
anything like this currently?
