type Retry ¶
type Retry struct {
InitialDelay time.Duration
MaximumDelay time.Duration
Factor float64
ErrCallback func(err error)
}
Retry is a concurrency safe retry structure that configures a simple backoff retry mechanism
func (*Retry) Do ¶
func (r *Retry) Do(ctx context.Context, logDescription string, f func(attempt int) (retry bool, err error)) error
Do invokes the function until the function returns false, or the retry pops. This simple interface doesn't pass through errors or return values, on the basis you'll be using a closure for that.
