Enum Either 

pub enum Either<Left, Right> {
    Left(Left),
    Right(Right),
}

A simple binary sum type.

This is occasionally useful in an ad hoc fashion.

Variants

Left(Left)

Right(Right)

Trait Implementations

impl<Left: Clone, Right: Clone> Clone for Either<Left, Right>

fn clone(&self) -> Either<Left, Right>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<Left: Debug, Right: Debug> Debug for Either<Left, Right>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<Left: PartialEq, Right: PartialEq> PartialEq for Either<Left, Right>

fn eq(&self, other: &Either<Left, Right>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
