Implementations

impl<A, B> EitherOrBoth<A, B>[src]

pub fn has_left(&self) -> bool[src]

If Left, or Both, return true, otherwise, return false.

pub fn has_right(&self) -> bool[src]

If Right, or Both, return true, otherwise, return false.

pub fn is_right(&self) -> bool[src]

If Right, return true otherwise, return false. Exclusive version of [has_right].
