Enum pour::BinaryResult

pub enum BinaryResult<T> {
    New(T),
    Left,
    Right,
    Ambi,
}

A binary result, which can be either the left value, the right value, or a new value

Used to avoid cloning

Variants

New(T)

A new value

Left

The left value

Right

The right value

Ambi

Either the left or the right, don't care
