2.3.3

Changes to -=

The -= operator was incorrectly changed to truncate bits that didn't correspond to valid flags in 2.3.0. This has been fixed up so it once again behaves the same as - and difference.

Changes to !

The ! operator previously called Self::from_bits_truncate, which would truncate any bits that only partially overlapped with a valid flag. It will now use bits & Self::all().bits(), so any bits that overlap any bits specified by any flag will be respected. This is unlikely to have any practical implications, but enables defining a flag like const ALL = !0 as a way to signal that any bit pattern is a known set of flags.

Changes to formatting

Zero-valued flags will never be printed. You'll either get 0x0 for empty flags using debug formatting, or the set of flags with zero-valued flags omitted for others.

Composite flags will no longer be redundantly printed if there are extra bits to print at the end that don't correspond to a valid flag.

What's Changed

• Fix up incorrect sub assign behavior and other cleanups by @​KodrAus in bitflags/bitflags#366
