Functions

func GetBit16

func GetBit16(v []byte, pos uint) uint8

func GetBit8

func GetBit8(v uint8, pos uint) uint8

@param pos: 取值范围 [0, 7]，0表示最低位

func GetBits16

func GetBits16(v []byte, pos uint, n uint) uint16

func GetBits8

func GetBits8(v uint8, pos uint, n uint) uint8

@param pos: 取值范围 [0, 7]，0表示最低位 @param n: 取多少位， 取值范围 [1, 8]

举例，GetBits8(105, 2, 4) = 10（即1010）

v: 0110 1001

pos: 2

n:   .. ..

Types

type BitReader

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

func NewBitReader

func NewBitReader(b []byte) BitReader

func (*BitReader) ReadBit

func (br *BitReader) ReadBit() uint8

func (*BitReader) ReadBits

func (br *BitReader) ReadBits(n uint) (r uint8)

目前限制一次最多读8位，大于8位可以分多次读，或者以后把限制放开

type BitWriter

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

func NewBitWriter

func NewBitWriter(b []byte) BitWriter

func (*BitWriter) WriteBit

func (bw *BitWriter) WriteBit(b uint8)

func (*BitWriter) WriteBits

func (bw *BitWriter) WriteBits(n int, v uint8)

目前限制一次最多写8位，大于8位可以分多次写，或者以后把限制放开
