type Book ¶
type Book struct {
Order []*Order // List of all orders in the book
Transactions []*Transaction // List of completed transactions
OrdersChan chan *Order // Input channel for receiving new orders
OrdersChanOut chan *Order // Output channel for sending processed ordes
Wg *sync.WaitGroup // WaitGroup for managing concurrent processing
}
