Types

type CallbackFuncs

type CallbackFuncs struct {
	StreamOpenFunc     func(context.Context, int64, string) error
	StreamClosedFunc   func(int64)
	StreamRequestFunc  func(int64, *discovery.DiscoveryRequest) error
	StreamResponseFunc func(int64, *discovery.DiscoveryRequest, *discovery.DiscoveryResponse)
	FetchRequestFunc   func(context.Context, *discovery.DiscoveryRequest) error
	FetchResponseFunc  func(*discovery.DiscoveryRequest, *discovery.DiscoveryResponse)
}

CallbackFuncs is a convenience type for implementing the Callbacks interface.

func (CallbackFuncs) OnFetchRequest

func (c CallbackFuncs) OnFetchRequest(ctx context.Context, req *discovery.DiscoveryRequest) error

OnFetchRequest invokes FetchRequestFunc.

func (CallbackFuncs) OnFetchResponse

func (c CallbackFuncs) OnFetchResponse(req *discovery.DiscoveryRequest, resp *discovery.DiscoveryResponse)

OnFetchResponse invoked FetchResponseFunc.

func (CallbackFuncs) OnStreamClosed

func (c CallbackFuncs) OnStreamClosed(streamID int64)

OnStreamClosed invokes StreamClosedFunc.

func (CallbackFuncs) OnStreamOpen

func (c CallbackFuncs) OnStreamOpen(ctx context.Context, streamID int64, typeURL string) error

OnStreamOpen invokes StreamOpenFunc.

func (CallbackFuncs) OnStreamRequest

func (c CallbackFuncs) OnStreamRequest(streamID int64, req *discovery.DiscoveryRequest) error

OnStreamRequest invokes StreamRequestFunc.

func (CallbackFuncs) OnStreamResponse

func (c CallbackFuncs) OnStreamResponse(streamID int64, req *discovery.DiscoveryRequest, resp *discovery.DiscoveryResponse)

OnStreamResponse invokes StreamResponseFunc.

type Callbacks

type Callbacks interface {
	rest.Callbacks
	sotw.Callbacks
}

Callbacks is a collection of callbacks inserted into the server operation. The callbacks are invoked synchronously.

type HTTPGateway

type HTTPGateway struct {
	// Log is an optional log for errors in response write
	Log log.Logger

	// Server is the underlying gRPC server
	Server Server
}

HTTPGateway is a custom implementation of [gRPC gateway](https://github.com/grpc-ecosystem/grpc-gateway) specialized to Envoy xDS API.

func (*HTTPGateway) ServeHTTP

func (h *HTTPGateway) ServeHTTP(req *http.Request) ([]byte, int, error)

type Server

Server is a collection of handlers for streaming discovery requests.

func NewServer

func NewServer(ctx context.Context, config cache.Cache, callbacks Callbacks) Server

NewServer creates handlers from a config watcher and callbacks.

func NewServerAdvanced

func NewServerAdvanced(restServer rest.Server, sotwServer sotw.Server) Server
