42 //! // Convert to/from the backing storage type.
66 //!   Signed integer storage types are not supported.
80 //! The macro generates the bitfield type, [`From`] and [`Into`] implementations for its storage
254 //! Bits of the storage type that are not part of any declared field are preserved by the setter
256 //! storage type.
280 //! Bitfield storage types are unsigned. Since field getter methods return a [`Bounded`] of the
281 //! storage type, fields are also unsigned by default.
