Enum Operand 

pub enum Operand<'a> {
    Zset(&'a Zset),
    Set(&'a Set),
    Missing,
}

One input to a sorted set operation.

A plain set is an operand because Redis says it is, and it behaves as a sorted set in which every member scores one.

Variants

Zset(&'a Zset)

A sorted set, with the scores it holds.

Set(&'a Set)

A plain set, where every member scores one.

Missing

A key that is not there, which is an empty input and not an error.
