func WithDeadlineBuffer ¶

func WithDeadlineBuffer(
	parent context.Context,
	timeout time.Duration,
	buffer time.Duration,
) (context.Context, context.CancelFunc)

WithDeadlineBuffer creates a child context with desired timeout. If buffer is non-zero, then child context timeout will be the minOf(parentCtx.Deadline()-buffer, maxTimeout). Use this method to create child context when childContext cannot use all of parent's deadline but instead there is a need to leave some time for parent to do some post-work
