Overview

Package grpc is a generated protocol buffer package.

It is generated from these files: 

fixtures_test.proto

It has these top-level messages: 

FixtureRequest
FixtureReply

Package grpc provides functions to trace the google.golang.org/grpc package v1.2.

Example (Client) 
package main

import (
	"log"

	grpctrace "gopkg.in/CodapeWild/dd-trace-go.v1/contrib/google.golang.org/grpc"

	"google.golang.org/grpc"
)

func main() {
	// Create the client interceptor using the grpc trace package.
	si := grpctrace.StreamClientInterceptor(grpctrace.WithServiceName("my-grpc-client"))
	ui := grpctrace.UnaryClientInterceptor(grpctrace.WithServiceName("my-grpc-client"))

	// Dial in using the created interceptor...
	conn, err := grpc.Dial("localhost:50051", grpc.WithInsecure(),
		grpc.WithStreamInterceptor(si), grpc.WithUnaryInterceptor(ui))
	if err != nil {
		log.Fatal(err)
	}
	defer conn.Close()

	// And continue using the connection as normal.
}

Output:
Example (Server) 
package main

import (
	"log"
	"net"

	grpctrace "gopkg.in/CodapeWild/dd-trace-go.v1/contrib/google.golang.org/grpc"

	"google.golang.org/grpc"
)

func main() {
	// Create a listener for the server.
	ln, err := net.Listen("tcp", ":50051")
	if err != nil {
		log.Fatal(err)
	}

	// Create the server interceptor using the grpc trace package.
	si := grpctrace.StreamServerInterceptor(grpctrace.WithServiceName("my-grpc-client"))
	ui := grpctrace.UnaryServerInterceptor(grpctrace.WithServiceName("my-grpc-client"))

	// Initialize the grpc server as normal, using the tracing interceptor.
	s := grpc.NewServer(grpc.StreamInterceptor(si), grpc.UnaryInterceptor(ui))

	// ... register your services

	// Start serving incoming connections.
	if err := s.Serve(ln); err != nil {
		log.Fatalf("failed to serve: %v", err)
	}
}

type FixtureRequest 

type FixtureRequest struct {
	Name string `protobuf:"bytes,1,opt,name=name" json:"name,omitempty"`
}

The request message containing the user's name.

func (*FixtureRequest) Descriptor 

func (*FixtureRequest) Descriptor() ([]byte, []int)

func (*FixtureRequest) GetName 

func (m *FixtureRequest) GetName() string

func (*FixtureRequest) ProtoMessage 

func (*FixtureRequest) ProtoMessage()

func (*FixtureRequest) Reset 

func (m *FixtureRequest) Reset()

type FixtureServer 

type FixtureServer interface {
	Ping(context.Context, *FixtureRequest) (*FixtureReply, error)
	StreamPing(Fixture_StreamPingServer) error
}

type Fixture_StreamPingClient added in v1.1.0 

type Fixture_StreamPingClient interface {
	Send(*FixtureRequest) error
	Recv() (*FixtureReply, error)
	grpc1.ClientStream
}

type Fixture_StreamPingServer added in v1.1.0 

type Fixture_StreamPingServer interface {
	Send(*FixtureReply) error
	Recv() (*FixtureRequest, error)
	grpc1.ServerStream
}

type InterceptorOption 

type InterceptorOption = Option

InterceptorOption represents an option that can be passed to the grpc unary client and server interceptors. InterceptorOption is deprecated in favor of Option.

func NonErrorCodes added in v1.12.0 

func NonErrorCodes(cs ...codes.Code) InterceptorOption
