pub enum EitherOrBoth<A, B> {
    Both(A, B),
    Left(A),
    Right(B),
}
Expand description

Value that either holds a single A or B, or both.

Variants

Both(A, B)

Both values are present.

Left(A)

Only the left value of type A is present.

Right(B)

Only the right value of type B is present.

Implementations

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

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

If Left, return true otherwise, return false. Exclusive version of has_left.

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

If Right, return true otherwise, return false. Equivalent to self.as_ref().both().is_some().

If Left, or Both, return Some with the left value, otherwise, return None.

If Right, or Both, return Some with the right value, otherwise, return None.

If Both, return Some tuple containing left and right.

Converts from &EitherOrBoth<A, B> to EitherOrBoth<&A, &B>.

Converts from &mut EitherOrBoth<A, B> to EitherOrBoth<&mut A, &mut B>.

Convert EitherOrBoth<A, B> to EitherOrBoth<B, A>.

Apply the function f on the value a in Left(a) or Both(a, b) variants. If it is present rewrapping the result in self’s original variant.

Apply the function f on the value b in Right(b) or Both(a, b) variants. If it is present rewrapping the result in self’s original variant.

Apply the functions f and g on the value a and b respectively; found in Left(a), Right(b), or Both(a, b) variants. The Result is rewrapped self’s original variant.

Apply the function f on the value a in Left(a) or Both(a, _) variants if it is present.

Apply the function f on the value b in Right(b) or Both(_, b) variants if it is present.

Returns a tuple consisting of the l and r in Both(l, r), if present. Otherwise, returns the wrapped value for the present element, and the default for the other.

Return either value of left, right, or the product of f applied where Both are present.
