NewBoundedWaitGroup initializes a new BoundedWaitGroup.

Retry attempts to execute the given callback function a certain number of times, with a delay between each attempt using a simple exponential backoff algorithm that uses a slight jitter to ensure that retries aren't clustered.

RetryStop wraps the given error in a private retryError type and returns it to signal that a retry loop should stop attempting the operation that produced the given error.

Yaml unmarshal limitation causes nested options objects to be decode as strings with json format ex: `{"foo": "bar"}` UnmarshalJsonObj performs unmarshal of jsons strings.

generic function to validate uniqueness across slice of attribute returned by f.

BoundedWaitGroup implements a sized WaitGroup.
