Hello All.
Is there a standard way to protect a field of a struct after
the struct has been initialized?
Is this possible with a struct?
If not, I suppose a class (object) would be needed? If so,
are there any simple pointers to an example of this?
Thanks in advance,

`private` works for structs the same as it does for classes.
https://dlang.org/spec/attribute.html#visibility_attributes
Perhaps you tried it, realized you could still access it within
the same module, and concluded that it didn't work? Consider
note #2 at that link: "Symbols with private visibility can only
be accessed from within the same module." Import the struct
into another module and test the visibility there and you'll
get the behavior you're looking for.
Hej JFondren,
Wow, thanks for the quick response. I had read that about the
modules ...
but as my test example had failed, I thought that I had
misunderstood
the larger picture.
Based on you kind reply, I went back over my example and found
that I
had been deceiving myself.
With a quick fix-up edit, it indeed is working as your
explanation.
Now, I proceed onto the trickier part of my endeavor ...
Thanks again, and Best Regards,
James
