Redis Set Commands

Provided Methods

fn sadd( self, key: impl Serialize, members: impl Serialize, ) -> PreparedCommand<'a, Self, usize>

Add the specified members to the set stored at key.

#Return The number of elements that were added to the set, not including all the elements already present in the set.

See Also

https://redis.io/commands/sadd/

fn scard(self, key: impl Serialize) -> PreparedCommand<'a, Self, usize>

Returns the set cardinality (number of elements) of the set stored at key.

Return

The cardinality (number of elements) of the set, or 0 if key does not exist.

See Also

https://redis.io/commands/scard/

fn sdiff<R: Response>( self, keys: impl Serialize, ) -> PreparedCommand<'a, Self, R>

Returns the members of the set resulting from the difference between the first set and all the successive sets.

Return

A list with members of the resulting set.

See Also

https://redis.io/commands/sdiff/

fn sdiffstore( self, destination: impl Serialize, keys: impl Serialize, ) -> PreparedCommand<'a, Self, usize>

This command is equal to sdiff, but instead of returning the resulting set, it is stored in destination.

Return

The number of elements in the resulting set.

See Also

https://redis.io/commands/sdiffstore/

fn sinter<R: Response>( self, keys: impl Serialize, ) -> PreparedCommand<'a, Self, R>

Returns the members of the set resulting from the intersection of all the given sets.

Return

A list with members of the resulting set.

See Also

https://redis.io/commands/sinter/

fn sintercard( self, keys: impl Serialize, limit: usize, ) -> PreparedCommand<'a, Self, usize>

This command is similar to sinter, but instead of returning the result set, it returns just the cardinality of the result.

limit: if the intersection cardinality reaches limit partway through the computation, the algorithm will exit and yield limit as the cardinality. 0 means unlimited

Return

A list with members of the resulting set.

See Also

https://redis.io/commands/sintercard/

fn sinterstore( self, destination: impl Serialize, keys: impl Serialize, ) -> PreparedCommand<'a, Self, usize>

This command is equal to sinter, but instead of returning the resulting set, it is stored in destination.

Return

The number of elements in the resulting set.

See Also

https://redis.io/commands/sinterstore/

fn sismember( self, key: impl Serialize, member: impl Serialize, ) -> PreparedCommand<'a, Self, bool>

Returns if member is a member of the set stored at key.

Return

• true - if the element is a member of the set.
• false - if the element is not a member of the set, or if key does not exist.

See Also

https://redis.io/commands/sismember/

fn smembers<R: Response>( self, key: impl Serialize, ) -> PreparedCommand<'a, Self, R>

Returns all the members of the set value stored at key.

See Also

https://redis.io/commands/smembers/

fn smismember<R: Response>( self, key: impl Serialize, members: impl Serialize, ) -> PreparedCommand<'a, Self, R>

Returns whether each member is a member of the set stored at key.

Return

list representing the membership of the given elements, in the same order as they are requested.

See Also

https://redis.io/commands/smismember/

fn smove( self, source: impl Serialize, destination: impl Serialize, member: impl Serialize, ) -> PreparedCommand<'a, Self, bool>

Move member from the set at source to the set at destination.

Return

• true - if the element is moved.
• false - if the element is not a member of source and no operation was performed.

See Also

https://redis.io/commands/smove/

fn spop<R: Response>( self, key: impl Serialize, count: usize, ) -> PreparedCommand<'a, Self, R>

Removes and returns one or more random members from the set value store at key.

Return

the list of popped elements

See Also

https://redis.io/commands/spop/

fn srandmember<R: Response>( self, key: impl Serialize, count: usize, ) -> PreparedCommand<'a, Self, R>

Removes and returns one or more random members from the set value store at key.

Return

the list of popped elements

See Also

https://redis.io/commands/srandmember/

fn srem( self, key: impl Serialize, members: impl Serialize, ) -> PreparedCommand<'a, Self, usize>

Remove the specified members from the set stored at key.

Return

the number of members that were removed from the set, not including non existing members.

See Also

https://redis.io/commands/srem/

fn sscan<R: Response + DeserializeOwned>( self, key: impl Serialize, cursor: u64, options: SScanOptions<'_>, ) -> PreparedCommand<'a, Self, (u64, R)>

Iterates elements of Sets types.

Return

a list of Set members.

See Also

https://redis.io/commands/sscan/

fn sunion<R: Response>( self, keys: impl Serialize, ) -> PreparedCommand<'a, Self, R>

Returns the members of the set resulting from the union of all the given sets.

Return

A list with members of the resulting set.

See Also

https://redis.io/commands/sunion/

fn sunionstore( self, destination: impl Serialize, keys: impl Serialize, ) -> PreparedCommand<'a, Self, usize>

This command is equal to sunion, but instead of returning the resulting set, it is stored in destination.

Return

The number of elements in the resulting set.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
