            Every rate-limit condition surfaced by litellm — whether it originated from

            an upstream LLM provider, a vendor batch endpoint, or one of litellm''s own

            proxy-side limiters (parallel-requests, dynamic-rate, batch-rate, budget,

            max-iterations, etc.) — is raised as an instance of this class.


            The :attr:`category` attribute lets callers distinguish the source. See

            :class:`RateLimitErrorCategory` for the available values.
