I'm using the protoc-gen-validate extensions to Protocol Buffer. I came across some other answers here but they didn't completely answer my question.
I'm trying to validate that the value passed into a field is a valid email, and that the field is populated. I tried the ignore_empty rule ( [(validate.rules).string.email = {required: true}];) but am getting an error since its not available for bool fields.
Is there a way to do this?
