Functions

func AnalyzeSuffix

func AnalyzeSuffix(uri string) (valid, hasStar, hasPlus, hasDollar, hasBang bool)

AnalyzeSuffix checks a given URI for schema validity and possession of characteristics

func ParseDuration

func ParseDuration(s string) (*time.Duration, error)

ParseDuration is a little like the existing time.ParseDuration but adds days and years because its really annoying not having that

func RestrictBy

func RestrictBy(from string, by string) (string, bool)

RestrictBy takes a topic, and a permission, and returns the intersection that represents the from topic restricted by the permission. It took a looong time to work out this logic...

func VerifyMVK

func VerifyMVK(mvk []byte) bool
