Bitty - bit array utilities for nim.
API: bitty
import bittytype BitArray
Creates an array of bits all packed in together.
BitArray = ref object
bits: seq[uint64]
len*: int
proc newBitArray
Create a new bit array.
proc newBitArray(len: int = 0): BitArray
proc []
Access a single bit.
proc `[]`(b: BitArray; i: int): bool {.raises: [IndexError].}
proc []=
Set a single bit.
proc `[]=`(b: BitArray; i: int; v: bool) {.raises: [IndexError].}
proc ==
Are two bit arrays the same.
proc `==`(a, b: BitArray): bool
proc and
And(s) two bit arrays returning a new bit array.
proc `and`(a, b: BitArray): BitArray {.raises: [ValueError].}
proc or
Or(s) two bit arrays returning a new bit array.
proc `or`(a, b: BitArray): BitArray {.raises: [ValueError].}
proc not
Not(s) or inverts a and returns a new bit array.
proc `not`(a: BitArray): BitArray
proc $
Turns the bit array into a string.
proc `$`(b: BitArray): string {.raises: [IndexError].}proc add
Add a bit to the end of the array.
proc add(b: BitArray; v: bool)proc hash
Computes a Hash for the bit array.
proc hash(b: BitArray): Hashtype BitArray2d
Creates an array of bits all packed in together.
