Usage
|
||
|
|
-----
|
||
|
|
|
||
|
|
```go
|
||
|
|
import "github.com/segmentio/backo-go"
|
||
|
|
|
||
|
|
// Create a Backo instance.
|
||
|
|
backo := backo.NewBacko(milliseconds(100), 2, 1, milliseconds(10*1000))
|
||
|
|
// OR with defaults.
|
||
|
|
backo := backo.DefaultBacko()
|
||
|
|
|
||
|
|
// Use the ticker API.
|
||
|
|
ticker := b.NewTicker()
|
||
|
|
for {
|
||
|
|
timeout := time.After(5 * time.Minute)
|
||
|
|
select {
|
||
|
|
case <-ticker.C:
|
||
|
|
fmt.Println("ticked")
|
||
|
|
case <- timeout:
|
||
|
|
fmt.Println("timed out")
|
||
|
|
}
|
||
|
|
}
|
||
|
|
|
||
|
|
// Or simply work with backoff intervals directly.
|
||
|
|
for i := 0; i < n; i++ {
|
||
|
|
// Sleep the current goroutine.
|
||
|
|
backo.Sleep(i)
|
||
|
|
// Retrieve the duration manually.
|
||
|
|
duration := backo.Duration(i)
|
||
|
|
}
|
||
|
|
