Distributed Computing with Go

The unidirectional buffer

Messages can be sent and received from a channel. However, when goroutines use channels for communication, they are generally going to be for a single purpose: either to send or receive from a channel. Go allows us to specify whether a channel being used by a goroutine is for sending or receiving messages. It accomplishes this with the help of unidirectional channels. Once a channel has been identified as being unidirectional, we cannot perform the other operation on them. This means that a unidirectional send channel cannot be used to receive messages, and a unidirectional receive channel cannot be used to send messages. Any attempts to do so would be caught by the Go compiler as compile-time errors.
