Go Select and Channels
Introduction
The
select keyword provides an easy method to work with channels and perform more advanced tasks. It is frequently used for a number of purposes: - Handling timeouts. - When there are multiple channels to read from, the select will randomly read from one channel which has data. - Providing an easy way to define what happens if no data is available on a channel.
Syntax
- select {}
- select { case true: }
- select { case incomingData := <-someChannel: }
- select { default: }
