### 9. retry is for executing a function repeatedly until it was successful or canceled by the context.
|
||||
|
||||
- Executes a function repeatedly until it was successful or canceled by the context.
|
||||
- Default retry times is 5, default retry duration is 3 second.
|
||||
- Usage: import "github.com/duke-git/lancet/retry".
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
"io/ioutil"
|
||||
"log"
|
||||
"github.com/duke-git/lancet/retry"
|
||||
)
|
||||
|
||||
func main() {
|
||||
var number int
|
||||
increaseNumber := func() error {
|
||||
number++
|
||||
if number == 3 {
|
||||
return nil
|
||||
}
|
||||
return errors.New("error occurs")
|
||||
}
|
||||
|
||||
err := retry.Retry(increaseNumber, retry.RetryDuration(time.Microsecond*50))
