The one thing Rust got right was inheriting the i64/u64/i32/u32/i8/u8 naming convention for types. Far more concise and unambiguously clear. No more typing unsigned long long int or uint64_t

I would have liked it more if it was U64 instead of u64, etc. It feels weird when all the other types are in PascalCase but then the primitive types are like this. Also str -> Str.
