Repeated enum validation not_in is not generated

[sashayakovtseva]

Affected versions: v0.0.14, v0.1.0

Input test.proto:

syntax = "proto3";

package test;

option go_package = "test";

import "validate.proto";

enum Status {
  STATUS_INVALID = 0;
  STATUS_A = 1;
  STATUS_B = 2;
  STATUS_C = 3;
}

message Request {
  repeated Status status = 1 [(validate.rules).repeated = {unique: true, items: {enum: {defined_only: true, not_in: [0]}}}];
}

Generate command:

protoc \
  -I . \
  -I $GOPATH/src/github.com/envoyproxy/protoc-gen-validate/validate \
  --go_out=":." \
  --validate_out="lang=go:." \
  test/test.proto

Expect: all validate rules are generated correclty.

Actual: rules are generated, but _Request_Status_NotInLookup is undefined.

Thanks for the super-clear reproducer!

I find that repeated.items.uint32.{in} is also seeing similar error.
