// This file imports other files generated from a build of protoc-gen-go
// locked to a specific version. For all imports, they were built using
// Go v1.13 and protoc v3.11.12. This package is used to test compatibility with
// checked in generated code that cannot easily change.
// As such, there should never be a need to update these generated files.
//
// The specific version of protoc-gen-go used is encoded in the file path:
//  ${NAME}_${COMMIT_DATE}_${COMMIT_HASH}/test.proto
//
// To avoid a dependency on the v1 module, we perform the following
// import path replacement to all generated .pb.go files:
//  "github.com/golang/protobuf/proto" =>
//  "google.golang.org/protobuf/internal/protolegacy"

// The oldest supported version of protoc-gen-go is 2fc053c5,
// which finished adding descriptor methods to all protobuf types.
