Types

type Addr

type Addr []byte

Addr represents a SOCKS address as defined in RFC 1928 section 5.

func ParseAddr

func ParseAddr(s string) Addr

ParseAddr parses the address in string s. Returns nil if failed.

func ReadAddr

func ReadAddr(r io.Reader) (Addr, error)

ReadAddr reads just enough bytes from r to get a valid Addr.

func SplitAddr

func SplitAddr(b []byte) Addr

SplitAddr slices a SOCKS address from beginning of b. Returns nil if failed.

func (Addr) Network

func (a Addr) Network() string

Network returns network name. Implements net.Addr interface.

func (Addr) String

func (a Addr) String() string

String serializes SOCKS address a to string form.
