Learning Functional Programming in Go

Receive order

Next, we execute the pipeline's Receive() function to wait for the orders to arrive on the output channel, and then we print out the order:

        pipeline.Receive(func(o Order){
              log.Printf("Received: %v", o)
       })
}

The following is the output:

order: &{10001 true alice,secret 7b/HWvtIB9a16AYk+Yv6WWwer3GFbxpjoR+GO9iHIYY= 0922 [{Apples 1 4.50} {Oranges 4 12.00}]} order: &{10002 true bob,secret EOc3kF/OmxY+dRCaYRrey8h24QoGzVU0/T2QKVCHb1Q= 0123 [{Milk 2 8.00} {Sugar 1 2.25} {Salt 3 3.75}]} Credit card XXXXXXXXXXXX1111 charged 16.50 Credit card XXXXXXXXXXXX5100 charged 14.00 2017/03/08 03:05:36 Close Pipeline 2017/03/08 03:05:36 Received: {10001 true alice,secret 4111111111111111 0922 [{Apples 1 4.50} {Oranges 4 12.00}]} 2017/03/08 03:05:36 ...
