Question to y'all:

Seeing the following code:

```rust
let mut arr = [0u8; 2];
arr.set_bit(0, true);
println!("{arr:X?}");
```

What do you think is/should be the output?
- A: `[0x01, 0x00]`
- B: `[0x00, 0x01]`

This came up during the development of my device-driver crate and I'd love to know what people think
