This looks like the wrong fix, as the lint suggets:

       --> relay-cabi/src/core.rs:138:50
        |
    138 |     if let Ok(uuid) = Uuid::from_slice(unsafe { &(*uuid).data[..] }) {
        |                                                  ^^^^^^^^^^^^^^^^
        |
        = note: creating a reference requires the pointer target to be valid and imposes aliasing requirements
        = note: `#[warn(dangerous_implicit_autorefs)]` on by default
    help: try using a raw pointer method instead; or if this reference is intentional, make it explicit
        |
    138 |     if let Ok(uuid) = Uuid::from_slice(unsafe { &(&(*uuid).data)[..] }) {
        |                                                  ++            +

Can we not avoid the reference?

I think replacing the from_slice calls with

Uuid::from_bytes(unsafe { (*uuid).data })

should do the trick. Also simplifies things a bit because from_bytes is not fallible (it takes the correct length by definition).

Oh nice, was trying to use u128 but that turns out does not have a stable ABI (today I learned)
