Functions

func ConnectTimeout 

func ConnectTimeout() time.Duration

ConnectTimeout returns the current connect timeout for new connections

func IdleTimeout 

func IdleTimeout() time.Duration

IdleTimeout returns the current idle timeout for new connections

func ReadTimeout 

func ReadTimeout() time.Duration

ReadTimeout returns the current read timeout for new connections

func SetConnectTimeout 

func SetConnectTimeout(t time.Duration)
