sequence

var Module = fx.Module(
	"vef:sequence",
	fx.Provide(
		fx.Annotate(
			sequence.NewMemoryStore,
			fx.As(fx.Self()),
			fx.As(new(sequence.Store)),
		),
		NewGenerator,
	),
	fx.Invoke(initStore),
)

Module provides the sequence generation functionality for the VEF framework.

The in-memory store backs the Generator by default and is also exposed as its concrete *sequence.MemoryStore, so applications can inject it and seed rules via MemoryStore.Register during their own start-up hook.

Applications can replace the backing store with a persistent or distributed one (e.g. sequence.NewDBStore or sequence.NewRedisStore) by decorating sequence.Store with vef.Decorate. When the active store implements contract.Initializer (as *sequence.DBStore does), initStore runs Init at start-up.
