• The helper function 'min' is used but not defined in this file, which might cause a compilation error. Consider defining or importing a min function.

		next := min(time.Duration(float64(last)*multiplier), maxInterval)

• The helper function 'min' is used but not defined, potentially causing a compilation error. Consider defining or importing an appropriate min function.

		e.currentInterval = min(time.Duration(float64(e.currentInterval)*e.multiplier), e.maxInterval)
