	assumedTagNames []string,
) ([]string, map[string]string, map[string]*Tag)

Types

type Options added in v1.0.71

type Options struct {
	Digest  string
	ImageID string
	Created int64
}

Options holds optional parameters for Tag creation

type Tag

type Tag struct {
	// contains filtered or unexported fields
}

Tag aggregates tag-related information: tag name, image digest etc

func Collect

func Collect(keys []string, tagNames map[string]string, tagMap map[string]*Tag) []*Tag

Collect organizes tags structures the way they could be used by API

func New

func New(name string, options Options) (*Tag, error)

New creates a new instance of Tag

func (*Tag) GetCreated

func (tg *Tag) GetCreated() int64

GetCreated gets image creation timestamp

func (*Tag) GetCreatedKey

func (tg *Tag) GetCreatedKey() string

GetCreatedKey gets image creation timestamp in a string form (for a string sort e.g.)
