Types

type Buffer

type Buffer struct {
	// contains filtered or unexported fields
}

func NewBuffer

func NewBuffer(data []byte) *Buffer

NewBuffer returns a buffer for bits sequence data. The bits sequence starts from MSB of the first byte.

func (*Buffer) Bytes

func (b *Buffer) Bytes() []byte

func (*Buffer) Len

func (b *Buffer) Len() int

Len returns the number of bits of the buffer.

func (*Buffer) ReadBit

func (b *Buffer) ReadBit() (uint8, error)

ReadBit reads one bit from b.

func (*Buffer) ReadBits

func (b *Buffer) ReadBits(n int) (uint64, error)

func (*Buffer) WriteBit

func (b *Buffer) WriteBit(bit uint8) error

WriteBit writes one bit to b.

func (*Buffer) WriteBitsLSB

func (b *Buffer) WriteBitsLSB(bits uint64, n int) error

WriteBitsLSB writes n bits of LSB to b. if n > 64, it panics.
