func NewAPI(
	appID string, appChannel channel.AppChannel,
	stateStores map[string]state.Store,
	secretStores map[string]secretstores.SecretStore,

	getComponentsFn func() []components_v1alpha.Component,
	shutdown func()) API

NewAPI returns a new gRPC API.

type ClientConnCloser

type ClientConnCloser interface {
	grpc.ClientConnInterface
	io.Closer
}

ClientConnCloser combines grpc.ClientConnInterface and io.Closer to cover the methods used from *grpc.ClientConn.

type Manager

type Manager struct {
	AppClient ClientConnCloser
	// contains filtered or unexported fields
}

Manager is a wrapper around gRPC connection pooling.

func NewGRPCManager

func NewGRPCManager(mode modes.DaprMode) *Manager

NewGRPCManager returns a new grpc manager.

func (*Manager) CreateLocalChannel

func (g *Manager) CreateLocalChannel(port, maxConcurrency int, spec config.TracingSpec, sslEnabled bool, maxRequestBodySize int, readBufferSize int) (channel.AppChannel, error)

CreateLocalChannel creates a new gRPC AppChannel.

func (*Manager) GetGRPCConnection

func (g *Manager) GetGRPCConnection(ctx context.Context, address, id string, namespace string, skipTLS, recreateIfExists, sslEnabled bool, customOpts ...grpc.DialOption) (*grpc.ClientConn, error)

GetGRPCConnection returns a new grpc connection for a given address and inits one if doesn't exist.

func (*Manager) SetAuthenticator

func (g *Manager) SetAuthenticator(auth security.Authenticator)

SetAuthenticator sets the gRPC manager a tls authenticator context.

type Server

type Server interface {
	io.Closer
	StartNonBlocking() error
}

Server is an interface for the dapr gRPC server.

func NewAPIServer
