BackOffRetry Operator

Overview

Implements a backoff retry if a source Observable sends an error, resubscribe to it in the hopes that it will complete without error.

The backoff configuration relies on github.com/cenkalti/backoff/v4.

Example

// Backoff retry configuration
backOffCfg := backoff.NewExponentialBackOff()
backOffCfg.InitialInterval = 10 * time.Millisecond

observable := rxgo.Defer([]rxgo.Producer{func(ctx context.Context, next chan<- rxgo.Item, done func()) {
	next <- rxgo.Of(1)
	next <- rxgo.Of(2)
	next <- rxgo.Error(errors.New("foo"))
	done()
}}).BackOffRetry(backoff.WithMaxRetries(backOffCfg, 2))

Output:

1
2
1
2
1
2
foo
