Functions

func LookupIP

func LookupIP(ctx context.Context, host string) (addrs []net.IP, err error)

LookupIP returns the given host's IP addresses.

Types

type Conn

type Conn struct {
	net.Conn
}

Conn represents a socket connection. It implements net.Conn.

func Dial

func Dial(ctx context.Context, protocol, addr string) (*Conn, error)

Dial connects to the address addr on the network protocol. The address format is host:port, where host may be a hostname or an IP address. Known protocols are "tcp" and "udp". The returned connection satisfies net.Conn, and is valid while ctx is valid; if the connection is to be used after ctx becomes invalid, invoke SetContext with the new context.

func DialTimeout

func DialTimeout(ctx context.Context, protocol, addr string, timeout time.Duration) (*Conn, error)

DialTimeout is like Dial but takes a timeout. The timeout includes name resolution, if required.

func (*Conn) KeepAlive

func (cn *Conn) KeepAlive() error

KeepAlive signals that the connection is still in use. It may be called to prevent the socket being closed due to inactivity.

func (*Conn) SetContext

func (cn *Conn) SetContext(ctx context.Context)

SetContext sets the context that is used by this Conn. It is usually used only when using a Conn that was created in a different context, such as when a connection is created during a warmup request but used while servicing a user request.
