Functions

func Pack

func Pack(formatStr string, msg interface{}) ([]byte, error)

StructsPack returns a byte slice containing the values of msg slice packed according to the given format. The items of msg slice must match the values required by the format exactly. Ex: structs.pack("H", 0) @example ```javascript const structs = require('nuclei/structs'); const packed = structs.Pack('H', [0]); ```

func StructsCalcSize

func StructsCalcSize(format string) (int, error)

StructsCalcSize returns the number of bytes needed to pack the values according to the given format. Ex: structs.CalcSize("H") @example ```javascript const structs = require('nuclei/structs'); const size = structs.CalcSize('H'); ```

func Unpack

func Unpack(format string, msg []byte) ([]interface{}, error)

StructsUnpack the byte slice (presumably packed by Pack(format, msg)) according to the given format. The result is a []interface{} slice even if it contains exactly one item. The byte slice must contain not less the amount of data required by the format (len(msg) must more or equal CalcSize(format)). Ex: structs.Unpack(">I", buff[:nb]) @example ```javascript const structs = require('nuclei/structs'); const result = structs.Unpack('H', [0]); ```
