Functions ¶
func GetIntLenc ¶
GetIntLenc 获取Length-Encoded-Integer的值 第二个返回值表示编码int相关的所有字节的长度 doc: https://dev.mysql.com/doc/internals/en/integer.html#fixed-length-integer
func GetIntN ¶
GetIntN 获取fixedInteger int<N>的值 doc: https://dev.mysql.com/doc/internals/en/integer.html#fixed-length-integer
func GetLenencInt ¶
GetLenencInt 获取Length-Encoded-Integer的值 返回值第二个int表示编码该int总共的字节数
func GetLenencString ¶
GetLenencString 获取length-encoded-string的值 doc: https://dev.mysql.com/doc/internals/en/string.html#packet-Protocol::LengthEncodedString
func GetLenencStringLength ¶
GetLenencStringLength 根据string值判断该值编码成lenencstr要占多少字节
func GetPacketHeader ¶
GetPacketHeader 获取pakcet头，简便方法，返回值第一个是payload长度，第二个是seqID
func GetStringFixed ¶
GetStringFixed 读取固定长度的string
func ReadEOFPacket ¶
ReadEOFPacket 读取一个EOF包，如果读取成功则返回true（会消费字节）
func ReadNULPacket ¶
ReadNULPacket 读取string[NUL]及0x00的index doc: https://dev.mysql.com/doc/internals/en/string.html#packet-Protocol::NulTerminatedString
