OptionalpageMaximum items per page. Forwarded to the underlying list call's
maxFileCount / maxKeyCount / maxPartCount parameter. B2 caps this
at endpoint-specific limits (typically 10000 for files, 100 for parts).
OptionalsignalAborts the iteration between fetches. When already aborted at call time,
the iterator throws immediately on its first next() call.
Note: this does NOT abort an in-flight HTTP request mid-page. The
iterator checks signal.throwIfAborted() only between fetches.
Options accepted by every
