type BitBool []bool

BitBool is a bit set implementation backed by a slice of bool values. It can dynamically grow to accommodate new elements.

func (b BitBool) Has(i int) bool

Has checks if the bit at position i is set. Returns false for any position beyond the current length.

func (b BitBool) Len() int

Len returns the total number of bits in the set.

func (b *BitBool) Set(i int, t bool)

Set sets or clears the bit at position i.

type BitUint8 []uint8

BitUint8 is a bit set implementation backed by a slice of uint8 values.

func NewBitUint8(n int) BitUint8

NewBitUint8 creates a new BitUint8 with capacity for at least n bits.

func (b BitUint8) Has(n int) bool

Has checks if the bit at position n is set.

func (b BitUint8) Len() int

Len returns the total number of bits in the set.

func (b *BitUint8) ReadFrom(r io.Reader) (n int64, err error)

ReadFrom implements io.ReaderFrom.

func (b BitUint8) Set(n int, t bool)

Set sets or clears the bit at position n.

func (b BitUint8) WriteTo(w io.Writer) (n int64, err error)

WriteTo implements io.WriterTo.
