   Good.  But for some reasons all the examples I have seen use   
   integer types like i32 and u64.

   I have read that there are C implementation (variants) where ptrdiff_t   
   and size_t are smaller than a pointer, in particular large-model C on   
   the 8086, and that was the reason for C standard restrictions about   
   pointer subtraction and pointer inequality comparison.   
      
   I hope nobody is doing large-model Rust, even though Rust may be more   
   appropriate for that than C.
