This function may have a small issue. After determining the closed state, it immediately unlocks the channel and sends a message. If the channel is closed after unlocking, sending the message may result in a “send on closed channel” error.

We believe defining an interface would be more user-friendly. Such as
type Service interface {
Send(ctx context.Context, msg *schema.ActivityMsg)
RegisterHandler(handler func(ctx context.Context, msg *schema.ActivityMsg) error)
Close()
}
func NewService() Service {
return queue.New[*schema.ActivityMsg]("activity", 128)
}
