C bitfields in Rust are hard
Basically I have this issue where I don't know how FFI should handle C bitfields. They're tricky, error-prone and implementation-defined.
How does Golang deal with this? It doesn't.
And to be fair, Rust doesn't either.
But then why does bindgen attempt to have bitfields at all. Yes,
I see the unsafe but wouldn't it be "safer" to recommend exporting C helper
functions to deal with this? I actually don't understand how any crate
can say they have "C-compatible" bitfields.
My mental model right now is: if the compilers are LLVM-based, then ABI should match up. This is most likely wrong.
