BitArray

A space-efficient bit array with RandomAccessCollection conformance in Swift.

Usage

Specify number of bits when creating an array:

var a = Array(3) // create an array of length 3
a[0] // false
a[1] = true
a[1] // true
let b = Array(a) // `b` has the same content as `a`.

Standard library protocols are honored:

let c: BitArray = [true, false, true]
let d = c.map { !$0 } // [false, true, false]
print(d) // "[false, true, false]"
c == d // false

See source code for more information.
