You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: health.pb.go
    path of file: ./repos/learning/golang/practice/go-crontab/gopath/src/github.com/coreos/etcd/vendor/google.golang.org/grpc/health/grpc_health_v1
    
    the code of the file until where you have to start completion: // Code generated by protoc-gen-go. DO NOT EDIT.
// source: grpc/health/v1/health.proto

package grpc_health_v1 // import "google.golang.org/grpc/health/grpc_health_v1"

import proto "github.com/golang/protobuf/proto"
import fmt "fmt"
import math "math"

import (
	context "golang.org/x/net/context"
	grpc "google.
    
func _Health_Check_Handler(srv interface{}, ctx context.Context, dec func(interface{}) error, interceptor grpc.UnaryServerInterceptor) (interface{}, error) {
	in := new(HealthCheckRequest)
	if err := dec(in); err != nil {
		return nil, err
	}
	if interceptor == nil {
		return srv.(HealthServer).Check(ctx, in)
	}
	info := &grpc.UnaryServerInfo{
		Server:     srv,
		FullMethod: "/grpc.health.v1.Health/Check",
	}
	handler := func(ctx context.Context, req interface{}) (interface{}, error) {
		return srv.(HealthServer).Check(ctx, req.(*HealthCheckRequest))
	}
	return interceptor(ctx, in, info, handler)
}
