GETBIT

Syntax

GETBIT key offset

Time complexity: O(1)

Returns the bit value at offset (zero-indexed) in the string value stored at key.

When offset is beyond the string length, the string is assumed to be a contiguous space with 0 bits. When key does not exist it is assumed to be an empty string, so offset is always out of range and the value is also assumed to be a contiguous space with 0 bits.

Return

Integer reply: the bit value stored at offset.

Examples

dragonfly> SET mykey "\x42"  # 0100'0010
dragonfly> GETBIT mykey 0
(integer) 0
dragonfly> GETBIT mykey 1
(integer) 1
dragonfly> GETBIT mykey 6
(integer) 1
dragonfly> GETBIT mykey 100
(integer) 0
