44 | // u64 currently allows negative numbers, and i64 allows numbers greater than `1<<63`. This is a | |
45 | // little counterintuitive, but since the discriminant can store all the bits, and extracting it | |
46 | // with a cast requires specifying the signedness, there is no loss of information in those cases. | |
47 | // This also applies to isize and usize on 64-bit targets. | |
