Enum joinkit::EitherOrBoth

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

A value yielded by merge_join and hash_join outer iterators. Contains one or two values, depending on which input iterator is exhausted.

Variants

Both(L, R)

Neither input iterator is exhausted yet, yielding two values.

Left(L)

The parameter iterator is exhausted, only yielding a value from the self iterator.

Right(R)

The self iterator is exhausted, only yielding a value from the parameter iterator.
