Constants

const HEXA_DIGITS = "0123456789abcdef" // used to convert a byte into hexa digit

Functions

func Append_hexastring

func Append_hexastring(dest []byte, source Mybin) []byte

Append_hexastring appends source in hexa notation, into dest string.

func Bin2uint64

func Bin2uint64(source Mybin) (uint64, *rsql.Error)

func Hexa2bin

func Hexa2bin(dest *Mybin, source []byte) *rsql.Error

Hexa2bin copies source string made of hexa digits into dest, converting hexa digits into binary bytes. Empty binary string "0x" is allowed, and the result is an empty byte slice.

The hexa string must begin with "0x", else, an error is returned. "0x" is followed by hexa digits, from most significant bytes (MSB) to least significant bytes (LSB) if considered as number, or first byte to last byte if stream of bytes.

An error is returned if a non-hexa digit is found.

Types

type Mybin

type Mybin []byte // byte at index 0 is MSB when considered as a number, and byte 0 when considered as stream of bytes. Note: cast(0x0401 as varbinary(1)) = 0x04, and cast(0x0401 as int) = 1025
