| We can use channels to synchronize execution across goroutines. Here's an example of using a blocking receive to wait for a goroutine to finish. When waiting for multiple goroutines to finish, you may prefer to use a [WaitGroup](waitgroups). | ||
package main |
||
import ( |
||
"fmt" |
||
"time" |
||
) |
||
| This is the function we'll run in a goroutine. The `done` channel will be used to notify another goroutine that this function's work is done. | func worker(done chan bool) { |
|
fmt.Print("working...") |
||
time.Sleep(time.Second) |
||
fmt.Println("done") |
||
| Send a value to notify that we're done. | done <- true |
|
} |
||
func main() { |
||
| Start a worker goroutine, giving it the channel to notify on. | done := make(chan bool, 1) |
|
go worker(done) |
||
| Block until we receive a notification from the worker on the channel. | <-done |
working...done |
} |
