I need a fast way to append to an SList. I was thinking of using
insertAfter()
and keep track of a range that points to the end of the list but, after
appending an item, how would you get the new range to the end?
This is what I had planned:
List!int list;
Range end = list[];
list.insertAfter(end, 42);
end = // How to get the new end?
end.popFront();
But it's slightly more complex than that. Because end is actually a null
pointer to begin with, it's not a valid range of the list. This is due to
the fact that SList is a struct. the first insert will generate a valid
range. So it should be like this:
List!int list;
list.insertFront(42); // first insert
auto end = list[]; // note, you can't use Range here, it would be
List!int.Range.
// from now on:
list.insertAfter(end, 21);
end.popFront();
