Add error support for custom validators #375

Open yamil-rivera opened 4 years ago

yamil-rivera commented 4 years ago

Currently, by rolling out our own validators using CustomTypeValidator interface, we cannot have a way to return a descriptive error for the validation that failed. Our only choice is to use the custom error message in the tag, but that one is really limited. Can the CustomTypeValidator interface be changed to return an error as well?

This is very important for complex validations that sometimes can't just have static error messages being returned from the struct. +1!
