Parameters ---------- size: int (optional) Nominal quantity for the value that corresponds to a complete transfer, e.g., total number of tiles or total number of bytes value: int (0) Starting internal counter value hooks: dict or None A dict of named functions to be called on each update. The signature of these must be ``f(size, value, **kwargs)`` Nc D||_||_|xsi|_||_yN)sizevaluehookskw)selfrr r kwargss N/var/www/skyplay_api_hub/venv/lib/python3.12/site-packages/fsspec/callbacks.py__init__zCallback.__init__s"  [b c|Srr s r __enter__zCallback.__enter__s rc$|jyrclose)r exc_argss r__exit__zCallback.__exit__"s  rcy)zClose callback.Nrrs rrzCallback.close%src T|j||||jdtS)a Return callback for child transfers If this callback is operating at a higher level, e.g., put, which may trigger transfers that can also be monitored. The function returns a callback that has to be passed to the child method, e.g., put_file, as `callback=` argument. The implementation uses `callback.branch` for compatibility. When implementing callbacks, it is recommended to override this function instead of `branch` and avoid calling `super().branched(...)`. Prefer using this function over `branch`.
