Description
Bitfields are commonly encountered when interacting with C code. Since many of the details of the behavior of bitfields are left to the implementation, it is hard to write cross-platform rust code that uses bitfields correctly. (Source: https://github.com/rust-lang/rfcs/pull/1449/)
Prior RFCs and other citations:
- https://github.com/rust-lang/rfcs/pull/1449
- This RFC was judged to be very-close to what we would want, but with certain specific details that needed to be included; a follow-up that takes a similar approach but addresses those questions would be welcome.
