def sAdd[W](key: String, members: W*)(implicit arg0: Writer[W]): Future[Long]

Adds one or more members to a set.

key: set key
members: member(s) to add
returns: the number of members added to the set, not including all the members that were already present

Since: 1.0.0
Exceptions thrown: [[scredis.exceptions.RedisErrorResponseException]] if key contains a value that is not a set

def sCard(key: String): Future[Long]

Returns the number of members in a set.

key: set key
returns: the cardinality (number of members) of the set, or 0 if key does not exist

Since: 1.0.0
Exceptions thrown: [[scredis.exceptions.RedisErrorResponseException]] if key contains a value that is not a set

def sDiff[R](key: String, keys: String*)(implicit arg0: Reader[R]): Future[Set[R]]

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

key: the key of the first set
keys: key(s) of successive set(s) whose members will be substracted from the first one
returns: the resulting set, or the empty set if the first key does not exist

Since: 1.0.0
Exceptions thrown: [[scredis.exceptions.RedisErrorResponseException]] if some keys contain a value that is not a set

def sDiffStore(destKey: String, key: String, keys: String*): Future[Long]

Stores the set resulting from the difference between the first set and all the successive sets.

destKey: key where to store the resulting set
key: key of first set
keys: keys of sets to be substracted from first set, if empty, first set is simply copied to destKey
returns: the cardinality of the resulting set

Since: 1.0.0
Exceptions thrown: [[scredis.exceptions.RedisErrorResponseException]] if some keys contain a value that is not a set
Note: If destKey already exists, it is overwritten.

def sInter[R](keys: String*)(implicit arg0: Reader[R]): Future[Set[R]]

Intersects multiple sets.

keys: keys of sets to be intersected together
returns: the resulting set, or the empty set if the first key does not exist

Since: 1.0.0
Exceptions thrown: [[scredis.exceptions.RedisErrorResponseException]] if some keys contain a value that is not a set

def sInterStore(destKey: String, keys: String*): Future[Long]

Intersects multiple sets and stores the resulting set in a key.

destKey: key where to store the resulting set
keys: keys of sets to be intersected together, if only one is specified, it is simply copied to destKey
returns: the cardinality of the resulting set

Since: 1.0.0
Exceptions thrown: [[scredis.exceptions.RedisErrorResponseException]] if some keys contain a value that is not a set
Note: If destKey already exists, it is overwritten.

def sIsMember[W](key: String, member: W)(implicit arg0: Writer[W]): Future[Boolean]

Determines if a given value is a member of a set.

key: set key
member: value to be tested
returns: true if the provided value is a member of the set stored at key, false otherwise

Since: 1.0.0
Exceptions thrown: [[scredis.exceptions.RedisErrorResponseException]] if key contains a value that is not a set

def sMembers[R](key: String)(implicit arg0: Reader[R]): Future[Set[R]]

Returns all the members of a set.

key: set key
returns: set stored at key, or the empty set if key does not exist

Since: 1.0.0
Exceptions thrown: [[scredis.exceptions.RedisErrorResponseException]] if key contains a value that is not a set

def sMove[W](sourceKey: String, destKey: String, member: W)(implicit arg0: Writer[W]): Future[Boolean]

Moves a member from one set to another.

sourceKey: key of source set
member: value to be moved from source set to destination set
returns: true if the member was moved, false if the element is not a member of source set and no operation was performed

Since: 1.0.0
Exceptions thrown: [[scredis.exceptions.RedisErrorResponseException]] if sourceKey or destKey contains a value that is not a set

def sPop[R](key: String)(implicit arg0: Reader[R]): Future[Option[R]]

Removes and returns a random member from a set.

key: set key
returns: random member, or None if key does not exist

Since: 1.0.0
Exceptions thrown: [[scredis.exceptions.RedisErrorResponseException]] if key contains a value that is not a set
Note: This operation is similar to SRANDMEMBER, that returns a random element from a set but does not remove it.

def sRandMember[R](key: String)(implicit arg0: Reader[R]): Future[Option[R]]

Returns a random member from a set (without removing it).

key: set key
returns: random member, or None if key does not exist

Since: 1.0.0
Exceptions thrown: [[scredis.exceptions.RedisErrorResponseException]] if key contains a value that is not a set

def sRandMembers[R](key: String, count: Int = 1)(implicit arg0: Reader[R]): Future[Set[R]]

Returns a random member from a set (without removing it).

key: set key
count: number of member to randomly retrieve
returns: set of random members, or the empty set if key does not exist

Since: 2.6.0
Exceptions thrown: [[scredis.exceptions.RedisErrorResponseException]] if key contains a value that is not a set

def sRem[W](key: String, members: W*)(implicit arg0: Writer[W]): Future[Long]

Removes one or more members from a set.

key: set key
members: members to remove from set
returns: the number of members that were removed from the set, not including non-existing members

Since: 1.0.0
Exceptions thrown: [[scredis.exceptions.RedisErrorResponseException]] if key contains a value that is not a set
Note: Redis versions older than 2.4 can only remove one member per call.

def sScan[R](key: String, cursor: Long, matchOpt: Option[String] = None, countOpt: Option[Int] = None)(implicit arg0: Reader[R]): Future[(Long, Set[R])]

Incrementally iterates the elements of a set.

cursor: the offset
matchOpt: when defined, the command only returns elements matching the pattern
countOpt: when defined, provides a hint of how many elements should be returned
returns: a pair containing the next cursor as its first element and the set of elements as its second element

Since: 2.8.0

def sUnion[R](keys: String*)(implicit arg0: Reader[R]): Future[Set[R]]

Computes the union of multiple sets.

keys: keys of sets to be included in the union computation
returns: the resulting set, or the empty set if the first key does not exist

Since: 1.0.0
Exceptions thrown: [[scredis.exceptions.RedisErrorResponseException]] if some keys contain a value that is not a set

def sUnionStore(destKey: String, keys: String*): Future[Long]

Computes the union of multiple sets and stores the resulting set in a key.

destKey: key where to store the resulting set
keys: keys of sets to be included in the union computation, if only one is specified, it is simply copied to destKey
returns: the cardinality of the resulting set

Since: 1.0.0
Exceptions thrown: [[scredis.exceptions.RedisErrorResponseException]] if some keys contain a value that is not a set
Note: If destKey already exists, it is overwritten.
