The BitOr trait enables the | operator for types that implement it. This operator is used for computing the bitwise or value of two integers, but has different meanings for various other data types.

Implementing BitOr looks like this:

pub enum BitExample {
    Yes,
    No,
}
impl BitOr for BitExample {
 type Output = BitExample;

 fn bitor(self, other: BitExample) -> BitExample {
        match (self, other) {
            (BitExample::Yes, BitExample::Yes) => BitExample::Yes,
            (BitExample::No, BitExample::Yes) => BitExample::Yes,
            (BitExample::Yes, BitExample::No) => BitExample::Yes,
            (BitExample::No, BitExample::No) => BitExample::No,
        }
    }
}
