pub fn set_union(&self, keys: Vec<String>) -> HandlerResult<SetQueryResponse>

Perform and return a set union on a given list of keys

pub fn set_intersection( &self, keys: Vec<String>, ) -> HandlerResult<SetQueryResponse>

Perform and return a set intersect on a given list of keys

pub fn set_query(&self, key: String) -> HandlerResult<SetQueryResponse>
