Protocol Buffers (protobuf) is a language-neutral binary serialization format. Define schemas in .proto files.

syntax = "proto3";
package myapp.v1;
option go_package = "github.com/myorg/myapp/gen/myappv1";

message User {
  string id = 1;
  string name = 2;
  string email = 3;
  int64 created_at = 4;
  repeated string roles = 5;       // ordered list
  Address address = 6;             // nested message
  UserStatus status = 7;           // enum
