Package retry v1.1.1

This library implements a retryer: a generic way to execute some code at regular interval.

Usage

Creating a new retryer is done with:

retry.New(retry.WithWaitDuration(10*time.Second), retry.WithMaxAttempts(5))

Possible options for the constructor are:

• WithWaitDuration: time interval between each execution of the code (default to 10 seconds).
• WithMaxDuration: the retryer will stop executing after the specified amount of time (disabled by default).
• WithMaxAttempts: the retryer will execute the at most N times. N being this max attempts parameter (default to 5).
• WithoutMaxAttempts: disable the max attempts parameter.

Then execute the retryer with:

err = retryer.Do(ctx, func(ctx context.Context) error {
    // ...
	})

The function given as parameter only returns an error. If this error has the type RetryCancelError, it stops the execution of the retryer. You can create such error with NewRetryCancelError.
