I'm not totally certain, but I believe issue may be that .draw_white()
is returning Option<&Card>
and it's not clear what the lifetime of the contained Card
should be. I believe it is the case that anytime you return a borrowed value, you must attach a lifetime to the borrowed value. Otherwise, the borrow checker cannot tell how long the borrowed value will live.
Maybe try the following definition for .draw_white()
instead
