ContextWithOptionalTimeout wraps context.WithTimeout and handles infinite timeouts expressed as 0 duration.

ListWatchUntil checks the provided conditions against the items returned by the list watcher, returning wait.ErrWaitTimeout if timeout is exceeded without all conditions returning true, or an error if an error occurs.

NewIndexerInformerWatcher will create an IndexerInformer and wrap it into watch.Interface so you can use it anywhere where you'd have used a regular Watcher returned from Watch method.

UntilWithoutRetry reads items from the watch until each provided condition succeeds, and then returns the last watch encountered.

UntilWithSync creates an informer from lw, optionally checks precondition when the store is synced, and watches the output until each provided condition succeeds, in a way that is identical to function UntilWithoutRetry.

ErrWatchClosed is returned when the watch channel is closed before timeout in UntilWithoutRetry.

ConditionFunc returns true if the condition has been reached, false if it has not been reached yet, or an error if the condition cannot be checked and should terminate.

PreconditionFunc returns true if the condition has been reached, false if it has not been reached yet, or an error if the condition failed or detected an error state.
