Functions

func AddIsolatorValueConstructor added in v0.4.0 

func AddIsolatorValueConstructor(n ACName, i IsolatorValueConstructor)

func SanitizeACName added in v0.4.0 

func SanitizeACName(s string) (string, error)

SanitizeACName replaces every invalid ACName character in s with a dash making it a legal ACName string. If the character is an upper case letter it replaces it with its lower case. It also removes illegal edge characters (hyphens, periods and slashes).

This is a helper function and its algorithm is not part of the spec. It should not be called without the user explicitly asking for a suggestion.

func ShortHash added in v0.2.0 

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.

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. Furthermore, the first and last character ("edges") must be alphanumeric, and an ACName cannot be empty. Programmatically, an ACName must conform to the regular expression ValidACName.

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