I'm working on a tutorial about gRPC. When I generated the .pb.go
file, I'm getting some XXX_*
type in my struct.
This is my consignment.proto
file:
syntax = "proto3";
package go.micro.srv.consignment;
service ShippingService {
rpc CreateConsignment(Consignment) returns (Response) {}
}
message Consignment {
string id = 1;
string description = 2;
int32 weight = 3;
repeated Container containers = 4;
string vessel_id = 5;
}
message Container {
string id = 1;
string customer_id = 2;
string origin = 3;
string user_id = 4;
}
message Response {
bool created = 1;
Consignment consignment = 2;
}
This is the struct in the .pb.go
file. Can someone tell me why are there 3 XXX
types in my struct
? Shouldn't the struct be reflecting what I'm defining in my proto
?
type Consignment struct {
Id string `protobuf:"bytes,1,opt,name=id" json:"id,omitempty"`
Description string `protobuf:"bytes,2,opt,name=description" json:"description,omitempty"`
Weight int32 `protobuf:"varint,3,opt,name=weight" json:"weight,omitempty"`
Containers []*Container `protobuf:"bytes,4,rep,name=containers" json:"containers,omitempty"`
VesselId string `protobuf:"bytes,5,opt,name=vessel_id,json=vesselId" json:"vessel_id,omitempty"`
XXX_NoUnkeyedLiteral struct{} `json:"-"`
XXX_unrecognized []byte `json:"-"`
XXX_sizecache int32 `json:"-"`
}
