Functions

func BuildAddress

func BuildAddress(ip string, port uint32) core.Address

BuildAddress returns a SocketAddress with the given ip and port.

func BuildProtoStruct

func BuildProtoStruct(value interface{}) *types.Struct

BuildProtoStruct builds a proto.Struct with the given value JSON encoded into a field called "value" in the struct.

func ConvertAddressToCidr

func ConvertAddressToCidr(addr string) *core.CidrRange

ConvertAddressToCidr converts from string to CIDR proto

func GetByAddress

func GetByAddress(listeners []*xdsapi.Listener, addr string) *xdsapi.Listener

GetByAddress returns a listener by its address TODO(mostrowski): consider passing map around to save iteration.

func GogoDurationToDuration

func GogoDurationToDuration(d *types.Duration) time.Duration

GogoDurationToDuration converts from gogo proto duration to time.duration

func MessageToStruct

func MessageToStruct(msg proto.Message) *types.Struct

MessageToStruct converts from proto message to proto Struct

func SortVirtualHosts

func SortVirtualHosts(hosts []route.VirtualHost)

SortVirtualHosts sorts a slice of virtual hosts by name.

Envoy computes a hash of the listener which is affected by order of elements in the filter. Therefore we sort virtual hosts by name before handing them back so the ordering is stable across HTTP Route Configs.
