Overview ¶

Package bus (piece ⑫) fans out domain events in memory: the web receives them over SSE, chat adapters re-edit messages already sent, and the scheduler re-plans reminders.

Types ¶

type Bus ¶

type Bus struct {
	// contains filtered or unexported fields
}

Bus is a non-blocking in-memory pub/sub. A slow subscriber loses events (its channel is buffered); consumers must refetch on gaps, as SSE clients do on reconnect (ADR 0013).

func New ¶

func New() *Bus

New returns an empty bus.

func (*Bus) Publish ¶

func (b *Bus) Publish(e Event)

Publish delivers e to every subscriber without blocking.

func (b *Bus) Subscribe(buffer int) (<-chan Event, func())

Subscribe returns a channel of events and a function to stop receiving.

type Event ¶

type Event struct {
	Type           string    `json:"type"`
	HouseholdID    string    `json:"householdId"`
	SubscriptionID string    `json:"subscriptionId,omitempty"`
	ChargeID       string    `json:"chargeId,omitempty"`
	EntityID       string    `json:"entityId,omitempty"`
	ActorLabel     string    `json:"actor,omitempty"`
	AuditID        string    `json:"auditId,omitempty"`
	At             time.Time `json:"at"`
}

Event describes something that changed.
