The bitwise exclusive-or (^) of the bits in self and other.

pub const fn complement(self) -> ContentHint

The bitwise negation (!) of the bits in self, truncating the result.

impl ContentHint

pub const fn iter(&self) -> Iter<ContentHint>

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

pub const fn iter_names(&self) -> IterNames<ContentHint>

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
