Types

type Handler

type Handler func(actor.Context, actor.Message) bool

Handler is a partial actor.Actor that can be composed with others

func All

func All(first Handler, rest ...Handler) Handler

All is a Handler composition that will only return true if all of its constituent Handlers returns true

func And

func And(l Handler, r Handler) Handler

And constructs a Handler that performs the left Handler, and if it returns true will return the result of performing the right Handler

func Any

func Any(first Handler, rest ...Handler) Handler

Any is a Handler composition that will return true the first time any of its constituent Handlers returns true

func Or

func Or(l Handler, r Handler) Handler

Or constructs a Handler that performs the left Handler, and if it returns false will return the result of performing the right Handler

func Panic

func Panic(h Handler) Handler

Panic wraps a Handler and will catch any panic value that is recovered in executing that Handler. These will be reported as a report.Error

func UnhandledMessage

func UnhandledMessage(h Handler) Handler

UnhandledMessage wraps a Handler and will report a report.DeadLetter if that Handler returns false

func (Handler) New

func (h Handler) New(_ ...actor.Arg) actor.Actor

New allows a Handler to act as a Factory of itself. Args are ignored and both panic and dead letter reporting are performed
