	// Infinity is the maximum possible duration for keepalive values
	Infinity = time.Duration(math.MaxInt64)

type Options

type Options struct {
	// After a duration of this time if the server/client doesn't see any activity it pings the peer to see if the transport is still alive.
	Time time.Duration
	// After having pinged for keepalive check, the server waits for a duration of Timeout and if no activity is seen even after that
	// the connection is closed.
	Timeout time.Duration
	// MaxServerConnectionAge is a duration for the maximum amount of time a
	// connection may exist before it will be closed by the server sending a GoAway.
	// A random jitter is added to spread out connection storms.
	// See
	MaxServerConnectionAge time.Duration // default value is infinity
	// MaxServerConnectionAgeGrace is an additive period after MaxServerConnectionAge
	// after which the connection will be forcibly closed by the server.
	MaxServerConnectionAgeGrace time.Duration // default value 10s

Options defines the set of options used for grpc keepalive. The Time and Timeout options are used for both client and server connections, whereas MaxServerConnectionAge* options are applicable on the server side only (as implied by the options' name...)
