This package implements value validations for structs and individual fields based on tags. 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

• 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 web framework
