Functions

func RTT

func RTT(conn net.Conn) (time.Duration, error)

RTT returns the RTT for the given net.Conn.

If the net.Conn is not a *net.TCPConn and cannot be unwrapped into one, then ErrNotTCP will be returned. If retrieving the RTT is not supported on the current platform, ErrUnimplemented will be returned.
