Enum Either

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

Sum type with two cases: Left and Right, used if a body can be one of two distinct types.

Variants

Left(L)

A value of type L

Right(R)

A value of type R

Implementations

impl<L> Either<L, L>

pub fn into_inner(self) -> L

Convert Either into the inner type, if both Left and Right are of the same type.
