This thing tested the lengths accordingly, of course.

Now Option<Box<Vec<u8>>> or Vec::with_capacity(262144) is not that
much shorter than doing something in C proper types at hand
provided.  (Btw C object constructors usually initialize their
types, too, .. that is why they are called constructors.
Of course: you need these objects, stdlib has none, but FILE,
which is horrific.  Vec<u8>, hmhm...)
