I have tried it (all of it) even before you wrote it here, because I have
completely the same ideas, but to be fair it has almost zero effect on
speed.
There is my version (It still use OOP, but I have try it wit Printer and
Counter to be structs and it has no effect at all)

The only difference in speed in the end is caused by hash implementation of
dlang associative arrays and rust HashMap, actually if you modify rust to
not used ahash it has almost same speed as D
