Overview

BitArray is an array data structure that compactly stores bits.

Bits externally represented as Bools are stored internally as UInt32s. The total number of bits stored is set at creation and is immutable.

NOTE To use BitArray, you must explicitly import it with require "bit_array"

Example

require "bit_array"

ba = BitArray.new(12) # => "BitArray[000000000000]"
ba[2]                 # => false
0.upto(5) { |i| ba[i * 2] = true }
ba    # => "BitArray[101010101010]"
ba[2] # => true
