The bitwise or (|) of the bits in self and other.

Source

pub fn remove(&mut self, other: Self)

The bitwise or (|) of the bits in self and other.

Source

pub const fn difference(self, other: Self) -> Self

The intersection of self with the complement of other (&!).

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.
