This makes me stupidly happy to see deleted.
This one also looks fine to me, albeit needs a touch of rebase it seems. |

Does this need to be an Option<&'static Class>
because it was initialized as 0 as *const Class
before? I think the only part that feels odd to me is the unsafe { DELEGATE_CLASS.unwrap() }
.

The static is created before the program begins, so it has to be initialized to some value, in this case None
. When the function is called the first time, the class is created and the static is set to the new value.
The unsafety in unsafe { DELEGATE_CLASS.unwrap() }
comes from the fact that DELEGATE_CLASS
is a mutable static, and hence can only be accessed behind unsafe
. Data races are prevented by Once
.
In essence, what we do here with DELEGATE_CLASS
and Once
is similar to once_cell::sync::Lazy
and the nightly std::cell::LazyCell
.
Where's this one sit with regards to #30? Should I just ignore it at this point? |
No, I'll pick it up again after #30 |
Kk sounds good! |

Is this still being worked on? It seems like the usage of beta |
No, I haven't worked on this crate in a long while, unfortunately. I still think there is value in what it is providing (a more rustic interface to Apple APIs), but my own focus has been on improving |
Builds upon #30.
