        Specified by:
        bitfield in interface ReactiveBitMapCommands<K>

      • bitpos

        public io.smallrye.mutiny.Uni<Long> bitpos​(K key,
                                           int bit)
        Description copied from interface: ReactiveBitMapCommands
        Execute the command BITPOS. Summary: Find first bit set or clear in a string Group: bitmap Requires Redis 2.8.7
        Specified by:
        bitpos in interface ReactiveBitMapCommands<K>
        Parameters:
        key - the key
        bit - 1 to look for 1, 0 to look for 0
        Returns:
        the position of the first bit set to 1 or 0 according to the request. If we look for set bits (the bit argument is 1) and the string is empty or composed of just zero ints, -1 is returned. If we look for clear bits (the bit argument is 0) and the string only contains bit set to 1, the function returns the first bit not part of the string on the right. So if the string is three ints set to the value 0xff the command BITPOS key 0 will return 24, since up to bit 23 all the bits are 1. Basically, the function considers the right of the string as padded with zeros if you look for clear bits and specify no range or the start argument only. However, this behavior changes if you are looking for clear bits and specify a range with both start and end. If no clear bit is found in the specified range, the function returns -1 as the user specified a clear range and there are no 0 bits in that range.
