  20. def hmset(key: Any, map: Iterable[Product2[Any, Any]])(implicit format: Format): Boolean

    Sets the specified fields to their respective values in the hash stored at key.

    Sets the specified fields to their respective values in the hash stored at key. This command overwrites any existing fields in the hash. If key does not exist, a new key holding a hash is created.

    map

    from fields to values

    returns

    True if operation completed successfully, False otherwise.

  22. def hset1(key: Any, field: Any, value: Any)(implicit format: Format): Option[Long]

    Sets field in the hash stored at key to value.

    Sets field in the hash stored at key to value. If key does not exist, a new key holding a hash is created. If field already exists in the hash, it is overwritten.

    returns

    Some(0) if field is a new field in the hash and value was set, Some(1) if field already exists in the hash and the value was updated.

  23. def hsetnx(key: Any, field: Any, value: Any)(implicit format: Format): Boolean

    Sets field in the hash stored at key to value, only if field does not yet exist.

    Sets field in the hash stored at key to value, only if field does not yet exist. If key does not exist, a new key holding a hash is created. If field already exists, this operation has no effect.

    returns

    True if field is a new field in the hash and value was set. False if field exists in the hash and no operation was performed.

    @deprecated
    Deprecated

    (Since version 3.2) Use the more idiomatic variant hgetall1, which has the returned Map behavior more consistent. See issue https://github.com/debasishg/scala-redis/issues/122

  2. def hset(key: Any, field: Any, value: Any)(implicit format: Format): Boolean

    Sets field in the hash stored at key to value.

    Sets field in the hash stored at key to value. If key does not exist, a new key holding a hash is created. If field already exists in the hash, it is overwritten.

    returns

    True if field is a new field in the hash and value was set, False if field already exists in the hash and the value was updated.

    Deprecated

    return value semantics is inconsistent with com.redis.HashOperations#hsetnx and com.redis.HashOperations#hmset. Use com.redis.HashOperations#hset1 instead
