Is there already a way to list metadata attributes?

I see::

    async def _getxattr(self, path, attr):
        """Get user-defined metadata attribute"""
        meta = (await self._info(path)).get("metadata", {})
        return meta[attr]

    getxattr = sync_wrapper(_getxattr)

Could we have as well something like:

    async def _listxattr(self, path, attr):
        """List all user-defined metadata attribute"""
        meta = (await self._info(path)).get("metadata", {})
        return meta

    listxattr = sync_wrapper(_listxattr)

My specific application is to check if a certain attribute exists and then x/y/z. I can do this at the moment with a try/except loop. If I had a list of available attributes then that would be a little cleaner.

Maybe this capability already exists?

Thanks, T.

Search the repository for the _getxattr and getxattr entry points shown in the issue, then inspect how metadata is retrieved and wrapped for synchronous use. Confirm whether an existing API already lists attributes; if not, done means exposing the available metadata attributes and covering the requested behavior with the repository’s relevant tests.
