Functions ¶

func BeDecode ¶

func BeDecode(b []byte, values ...interface{}) error

整形二进制解包，注意第二个及其后参数为字长确定的整形变量的指针地址，以便确定解析的[]byte长度，例如：int8/16/32/64、uint8/16/32/64、float32/64等等

func BeDecodeToFloat32 ¶

func BeDecodeToFloat32(b []byte) float32

func BeDecodeToFloat64 ¶

func BeDecodeToFloat64(b []byte) float64

func BeDecodeToInt ¶

func BeDecodeToInt(b []byte) int

将二进制解析为int类型，根据[]byte的长度进行自动转换. 注意内部使用的是uint*，使用int会造成位丢失。

func BeDecodeToInt16 ¶

func BeDecodeToInt16(b []byte) int16

func BeDecodeToInt32 ¶

func BeDecodeToInt32(b []byte) int32

func BeDecodeToInt64 ¶

func BeDecodeToInt64(b []byte) int64

func BeDecodeToInt8 ¶

func BeDecodeToInt8(b []byte) int8

func BeDecodeToString ¶

func BeDecodeToString(b []byte) string

func BeDecodeToUint16 ¶

func BeDecodeToUint16(b []byte) uint16

func BeDecodeToUint32 ¶

func BeDecodeToUint8 ¶

func BeEncode ¶

func BeEncode(values ...interface{}) []byte

BeEncode encodes one or multiple <values> into bytes using BigEndian. It uses type asserting checking the type of each value of <values> and internally calls corresponding converting function do the bytes converting.

It supports common variable type asserting, and finally it uses fmt.Sprintf converting value to string and then to bytes.

func BeEncodeBool ¶

func BeEncodeBool(b bool) []byte

func BeEncodeByLength ¶

func BeEncodeByLength(length int, values ...interface{}) []byte

将变量转换为二进制[]byte，并指定固定的[]byte长度返回，长度单位为字节(byte)；如果转换的二进制长度超过指定长度，那么进行截断处理

func BeEncodeFloat32 ¶

func BeEncodeFloat32(f float32) []byte

func BeEncodeFloat64 ¶

func BeEncodeFloat64(f float64) []byte

func BeEncodeInt ¶

func BeEncodeInt(i int) []byte

自动识别int类型长度，转换为[]byte

func BeEncodeInt16 ¶

func BeEncodeInt16(i int16) []byte

func BeEncodeInt32 ¶

func BeEncodeInt32(i int32) []byte

func BeEncodeInt64 ¶

func BeEncodeInt64(i int64) []byte

func BeEncodeInt8 ¶

func BeEncodeInt8(i int8) []byte

func BeEncodeString ¶

func BeEncodeString(s string) []byte
