func Get[I constraints.Integer](data []byte, n I) int

Get returns the value of the n'th bit (0 or 1).

func Ones(data []byte) iter.Seq[int]

Ones iterates over the indexes of bits whose values are 1.

func Set[I constraints.Integer](data []byte, n I, value bool)

Set sets the n'th bit to 1 or 0 for values of true or false respectively.

func Set0[I constraints.Integer](data []byte, n I)

Set0 sets the n'th bit in data to 0.

func Set1[I constraints.Integer](data []byte, n I)

Set1 sets the n'th bit in data to 1.

func Sum(data []byte) int

Sum returns the number of bits that have a value of 1.

func Zeros(data []byte) iter.Seq[int]

Zeros iterates over the indexes of bits whose values are 0.
