v0.5.0

New Features

Support JSON marshalling and unmarshalling for the Route struct value #14

Examples

Marshalling

func ExampleRoute_MarshalJSON() {
	r := &Route{
		Destination: &net.IPNet{
			IP:   net.IPv4(192, 0, 2, 0).To4(),
			Mask: net.IPv4Mask(255, 255, 255, 0),
		},
		Gateway:          net.IPv4(192, 0, 2, 1),
		NetworkInterface: "ifb0",
		Metric:           1,
	}

	marshalled, err := json.Marshal(r)
	if err != nil {
		panic(err)
	}
	fmt.Printf("%s\n", marshalled)

	// Output:
	// {"destination":"192.0.2.0/24","gateway":"192.0.2.1","networkInterface":"ifb0","metric":1}
}

Unmarshalling

func ExampleRoute_UnmarshalJSON() {
	var r Route
	err := json.Unmarshal([]byte(`{"destination":"192.0.2.0/24","gateway":"192.0.2.1","networkInterface":"ifb0","metric":1}`), &r)
	if err != nil {
		panic(err)
	}

	fmt.Printf("destination: %s\n", r.Destination.String())
	fmt.Printf("gateway: %s\n", r.Gateway.String())
	fmt.Printf("networkInterface: %s\n", r.NetworkInterface)
	fmt.Printf("metric: %d\n", r.Metric)

	// Output:
	// destination: 192.0.2.0/24
	// gateway: 192.0.2.1
	// networkInterface: ifb0
	// metric: 1
}

v0.4.0

v0.2.1

Performance Improvements

Prune a non-terminated branch on route removal #8

This change makes it prune a non-terminated branch on route removal. This change brings up better performance for routes searching like the following benchmark result:

Maintenance

• Simplify the logic in addRoute() #9

v0.2.0

What's Changed

Breaking Changes

• Change the signatures that use net.IPNet #4

New Features

• Add an operation "ClearRoutes" to remove all routes from the routing table #5
• Remove an associated label mapping when it removes by RemoveRoute() instead of RemoveRouteByLabel() #6

Maintenance

• Organize the code structure #3
