6 GB of RAM and 14 GB of swap are surely enough, since I can build rust on
my system with 4 GB of RAM and 2 GB of swap.

I suspect the poudriere's jail has not access to all of that memory for some
reason or some other process in your system eats much memory. The
poudriere's jail itself surely eats some: I do not know how much, but I do not
think it is a small amount.
