Functions

func ShortHash 

func ShortHash(hash string) string

Types

type ACKind 

type ACKind string

ACKind wraps a string to define a field which must be set with one of several ACKind values. If it is unset, or has an invalid value, the field will refuse to marshal/unmarshal.

func (ACKindError) Error 

func (e ACKindError) Error() string

type ACName 

type ACName string

ACName (an App-Container Name) is a format used by keys in different formats of the App Container Standard. An ACName is restricted to characters accepted by the DNS RFC[1] and "/"; all alphabetical characters must be lowercase only.

[1] http://tools.ietf.org/html/rfc1123#page-13
