You could use zram[1], it's like a ramdisk but compressed. Source code compresses very good, binary files compress to ~50% in my tests. > I know I could plump for the -bin package. Maybe I should.

You could create /var/tmp/portage/dev-lang/rust after creating the ramdisk and then bind-mount another directory to it. But then you'd have to tell portage to not delete it with FEATURES="keepwork"[2] (see`man 5 make.conf`) … I wouldn't recommend it.
