Functions

func Enable

func Enable(server *prpc.Server)

Enable registers a discovery service in the server.

It makes all services registered in the server (now or later), including the discovery service itself, discoverable.

func FileDescriptorSet

func FileDescriptorSet() *descriptorpb.FileDescriptorSet

FileDescriptorSet returns a descriptor set for this proto package, which includes all defined services, and all transitive dependencies.

Will not return nil.

Do NOT modify the returned descriptor.

func GetDescriptorSet

func GetDescriptorSet(serviceName string) (*descriptorpb.FileDescriptorSet, error)

GetDescriptorSet returns a descriptor set that contains the request service, its message types and all transitive dependencies. Returns (nil, nil) if the service descriptor is unknown.

Do NOT modify the returned descriptor.

func RegisterDescriptorSetCompressed

func RegisterDescriptorSetCompressed(serviceNames []string, compressedDescriptorSet []byte)

RegisterDescriptorSetCompressed registers a descriptor set for a set of services. Called from code generated by go.chromium.org/luci/grpc/cmd/cproto

compressedDescriptorSet must be a valid descriptor.FileDescriptorSet message compressed with gzip. It must contain descriptions for all the services, their message types and all transitive dependencies.

This call is cheap.

func RegisterDiscoveryServer

func RegisterDiscoveryServer(s prpc.Registrar, srv DiscoveryServer)

Types

type DescribeResponse

type DescribeResponse struct {

	// Description contains descriptions of all services, their types and all
	// transitive dependencies.
	Description *descriptorpb.FileDescriptorSet `protobuf:"bytes,1,opt,name=description,proto3" json:"description,omitempty"`
	// Services are service names provided by a server.
	Services []string `protobuf:"bytes,2,rep,name=services,proto3" json:"services,omitempty"`
	// contains filtered or unexported fields
}

DescribeResponse describes services.

func (*DescribeResponse) Descriptor deprecated

This method has been deprecated.
func (*DescribeResponse) Descriptor() ([]byte, []int)

Deprecated: Use DescribeResponse.ProtoReflect.Descriptor instead.

func (*DescribeResponse) GetDescription

func (x *DescribeResponse) GetDescription() *descriptorpb.FileDescriptorSet

func (*DescribeResponse) GetServices

func (x *DescribeResponse) GetServices() []string

func (*DescribeResponse) ProtoMessage

func (*DescribeResponse) ProtoMessage()

func (*DescribeResponse) ProtoReflect

func (x *DescribeResponse) ProtoReflect() protoreflect.Message

func (*DescribeResponse) Reset

func (x *DescribeResponse) Reset()

func (*DescribeResponse) String

func (x *DescribeResponse) String() string

type DiscoveryClient

type DiscoveryClient interface {
	// Describe returns a list of services and a descriptor.FileDescriptorSet
	// that covers them all.
	Describe(ctx context.Context, in *Void, opts ...grpc.CallOption) (*DescribeResponse, error)
}

DiscoveryClient is the client API for Discovery service.

For semantics around ctx use and closing/ending streaming RPCs, please refer to https://godoc.org/google.golang.org/grpc#ClientConn.NewStream.

func NewDiscoveryClient

func NewDiscoveryClient(cc grpc.ClientConnInterface) DiscoveryClient

func NewDiscoveryPRPCClient

func NewDiscoveryPRPCClient(client *prpc.Client) DiscoveryClient

type DiscoveryServer

type DiscoveryServer interface {
	// Describe returns a list of services and a descriptor.FileDescriptorSet
	// that covers them all.
	Describe(context.Context, *Void) (*DescribeResponse, error)
}

DiscoveryServer is the server API for Discovery service.

func New

func New(serviceNames ...string) DiscoveryServer

New creates a discovery server for all given services.

Service names have form "<pkg>.<service>", where "<pkg>" is name of the proto package and "<service>" is name of the service in the proto.

The service descriptions must be registered already using RegisterDescriptorSetCompressed which is called by init() function generated by go.chromium.org/luci/grpc/cmd/cproto.

type UnimplementedDiscoveryServer

type UnimplementedDiscoveryServer struct {
}

UnimplementedDiscoveryServer can be embedded to have forward compatible implementations.

func (*UnimplementedDiscoveryServer) Describe

type Void

type Void struct {
	// contains filtered or unexported fields
}

Void is an empty message.

func (*Void) Descriptor deprecated

This method has been deprecated.
func (*Void) Descriptor() ([]byte, []int)

Deprecated: Use Void.ProtoReflect.Descriptor instead.

func (*Void) ProtoMessage

func (*Void) ProtoMessage()

func (*Void) ProtoReflect

func (x *Void) ProtoReflect() protoreflect.Message

func (*Void) Reset

func (x *Void) Reset()

func (*Void) String

func (x *Void) String() string
