This helper is server-side only and is intended for caching internal async dependencies such as auth or metadata lookups. Args: key: Cache key. loader: Async callable that fetches the value on miss/revalidation. fresh_for: How long a cached value is considered fresh (no revalidation). Defaults to ``timedelta(0)`` so every access triggers a background revalidate while still returning the cached value instantly. Values above :data:`MAX_CACHE_TTL` are clamped to the backend maximum. max_age: Total lifetime of a cached entry. After this, the next access blocks on the loader. Defaults to :data:`MAX_CACHE_TTL` (24 h by default). Values above :data:`MAX_CACHE_TTL` are clamped to the backend maximum. model: Optional Pydantic model class. When provided, values are serialized via ``model_dump(mode="json")`` before storage and deserialized via ``model.model_validate()`` on read. Returns: An :class:`SWRResult` with ``.value``, ``.status``, and an async ``.mutate()`` method. Semantics: - cache miss: await ``loader()``, store the value, return it - fresh hit (age < fresh_for): return the cached value - stale hit (fresh_for <= age < max_age): return the cached value immediately and trigger a best-effort background refresh - expired (age >= max_age): await ``loader()``, store the value, return it Nr)r)daysr0)_api_swrr+r)r,loaderr1r2r3s rrr]s_N B  aL # y  s;AAA)r,strrz Any | None)r,r9rrr-timedelta | NonerNone) r,r9r8zCallable[[], Awaitable[T]]r1r:r2r:r3ztype[T] | Nonerz SWRResult[T])r$ __future__rcollections.abcrrdatetimertypingrrr r r rlanggraph_api.cacherr*rr/ ImportErrorrrr7__all__rr'rrCs#/11 CL9:  -3&  !FJ&.#' $ 2 2 &2 2  2  22IJJH GAJ s" A3 B3 B?BBB
