Tag stores the parsed data from the tag string in a struct field. These are all optional.

func ParseTag

func ParseTag(raw string) (*Tag, error)

ParseTag parses a tag string from the struct field and unmarshals into a Tag struct.

func (*Tag) ParentReference

func (tag *Tag) ParentReference() (string, string)

func (*Tag) Validate

func (tag *Tag) Validate() error

type Tags

type Tags map[string]*Tag

func ReadTagsFile

func ReadTagsFile(file string) (Tags, error)

func (Tags) String

func (tags Tags) String() string
