 It has the following **unique** features:
 
--   Cross Field and Cross Struct validations by using validation tags or custom validators.
--   Slice, Array and Map diving, which allows any or all levels of a multidimensional field to be validated.
--   Ability to dive into both map keys and values for validation
--   Handles type interface by determining it's underlying type prior to validation.
--   Handles custom field types such as sql driver Valuer see [Valuer](https://golang.org/src/database/sql/driver/types.go?s=1210:1293#L29)
--   Alias validation tags, which allows for mapping of several validations to a single tag for easier defining of validations on structs
--   Extraction of custom defined Field Name e.g. can specify to extract the JSON name while validating and have it available in the resulting FieldError
--   Customizable i18n aware error messages.
--   Default validator for the [gin](https://github.com/gin-gonic/gin) web framework; upgrading from v8 to v9 in gin see [here](https://github.com/go-playground/validator/tree/master/_examples/gin-upgrading-overriding)

 Validator returns only InvalidValidationError for bad validation input, nil or ValidationErrors as type error; so, in your code all you need to do is check if the error returned is not nil, and if it's not check if error is InvalidValidationError ( if necessary, most of the time it isn't ) type cast it to type ValidationErrors like so:
