Types ¶

type BitSet ¶

type BitSet interface {
	Get(i uint) bool
	Set(i uint)
	Unset(i uint)
	SetBool(i uint, b bool)
}

BitSet the bitset interface

type Bytes ¶

type Bytes []byte

Bytes the bitset []byte

func NewBytes ¶

func NewBytes(numBits uint) Bytes

NewBytes returns a new bitset that is capable of holding numBits number of binary values. All bytes in the bitset are zeroed and each bit is therefore considered unset.

func (Bytes) Get ¶

func (s Bytes) Get(i uint) bool

Get returns whether the bit at index i is set or not. This method will panic if the index results in a byte index that exceeds the number of bytes held by the bitset.

func (*Bytes) Grow ¶

func (s *Bytes) Grow(numBits uint)

Grow ensures that the bitset s is large enough to hold numBits number of bits, potentially appending to and/or reallocating the slice if the current length is not sufficient.

func (Bytes) Set ¶

func (s Bytes) Set(i uint)

Set sets the bit at index i. This method will panic if the index results in a byte index that exceeds the number of a bytes held by the bitset.

func (Bytes) SetBool ¶

func (s Bytes) SetBool(i uint, b bool)

SetBool sets or unsets the bit at index i depending on the value of b. This method will panic if the index results in a byte index that exceeds the nubmer of bytes held by the bitset.

func (Bytes) String ¶

func (s Bytes) String() string

String eq: `[4 0] bit(00100000 00000000)`

func (Bytes) Unset ¶

func (s Bytes) Unset(i uint)

Unset unsets the bit at index i. This method will panc if the index results in a byte index that exceeds the number of bytes held by the bitset.
