Functions

func Unpack added in v0.19.0 

func Unpack(env *Envelope) (dogma.Message, error)

Unpack returns the message contained within an envelope. TODO: Make `UnpackCommand`, etc.

func WithBaggage added in v0.22.0 

func WithBaggage(x proto.Message) interface {
	PackCommandOption
	PackEffectsOption
	PackEffectCommandOption
	PackEffectEventOption
	PackEffectTimeoutOption
}

WithBaggage adds x to the envelope's baggage.

Baggage applies to the envelope being packed and is inherited by downstream messages in the causal chain.

func WithExtension added in v0.22.0 

func WithExtension(x proto.Message) interface {
	PackCommandOption
	PackEffectsOption
	PackEffectCommandOption
	PackEffectEventOption
	PackEffectTimeoutOption
}

WithExtension adds x to the envelope's extensions.

Extensions apply only to the envelope being packed; they are not inherited by downstream messages in the causal chain.
