Oh, ick. 34 bits total of wastage? Sure, struct alignment would mean the same wastage in arrays, but still...

This is really reinforcing my preference for Rust's [ui]{64,32,16,8} integer types over C's (unsigned) {long long,long,int,short,char} fuzzily-sized ones :/

(and Rust then has usize, defined as "capable of holding a pointer", for the cases where that's relevant)

Are the Rust types not exactly the same as the long established C99 <stdint.h> or C++11 <cstdint>? I haven't used the "fuzzy" types much in over a decade!

They are exactly that - but when POSIX defines things in terms of the fuzzy types, even the sensible people who use stdint can't escape.

(of course, for FFI there's libc::c_int and so on, but that's just it: for FFI.)
