Struct redis_driver::ZInterUnion

pub struct ZInterUnion<'a, T>where
    T: SortedSetCommands + ?Sized,{ /* private fields */ }

Builder for the zinter and zunion commands

Implementations

impl<'a, T> ZInterUnion<'a, T>where
    T: SortedSetCommands + ?Sized,

pub fn weights<W>(self, weights: W) -> Selfwhere
    W: SingleArgOrCollection<f64>,

Using the WEIGHTS option, it is possible to specify a multiplication factor for each input sorted set.

This means that the score of every element in every input sorted set is multiplied by this factor before being passed to the aggregation function. When WEIGHTS is not given, the multiplication factors default to 1.

pub fn aggregate(self, aggregate: ZAggregate) -> Self

With the AGGREGATE option, it is possible to specify how the results of the union are aggregated.

This option defaults to SUM, where the score of an element is summed across the inputs where it exists. When this option is set to either MIN or MAX, the resulting set will contain the minimum or maximum score of an element across the inputs where it exists.

pub fn execute<E>(self) -> Pin<Box<dyn Future<Output = Result<Vec<E>>> + 'a>>where
    E: FromValue,

The result of the intersection

pub fn with_scores<E>(
    self
) -> Pin<Box<dyn Future<Output = Result<Vec<(E, f64)>>> + 'a>>where
    E: FromValue,

The result of the intersection with scores
