Method: BitPack#on

Defined in:
ext/bitpack/bitpack_ext.c

#on(i) ⇒ Object

Sets the bit at index i. If i is greater than the current size of the BitPack object, then the size is expanded and the current append position is set to this index.

Example

>> bp = BitPack.new
=>
>> bp.on(0)
=> 1
>> bp.on(2)
=> 101
>> bp.on(7)
=> 10100001
>> bp.on(6)
=> 10100011
