What happens when I use i64 on a 32 bit machine

I don’t have access to a 32 bit machine, so I can’t test this out, but what happens when you make the type of something i64 on a 32 bit machine? Does it behave like an i32, or does rust represent it by multiple integer types (similar to javs’s BigNumber)?

If the hardware of your target doesn't natively support i64, operations will be implemented in software. It always behaves the same, regardless of the platform.


Note that many 32-bit architectures do have native support for 64-bit integers (as well as 32-bit, 16-bit, and 8-bit integers).
