          token (`str` or `bool`, *optional*):
              A token to be used for the download.
                  - If `True`, the token is read from the HuggingFace config
                    folder.
                  - If `False` or `None`, no token is provided.
                  - If a string, it's used as the authentication token.
          proxies (`dict`, *optional*):
              Dictionary mapping protocol to the URL of the proxy passed to
              `requests.request`.
          timeout (`float`, *optional*, defaults to 10):
              How many seconds to wait for the server to send metadata before giving up.
          library_name (`str`, *optional*):
              The name of the library to which the object corresponds.
          library_version (`str`, *optional*):
              The version of the library.
          user_agent (`dict`, `str`, *optional*):
              The user-agent info in the form of a dictionary or a string.
  
      Returns:
          A [`HfFileMetadata`] object containing metadata such as location, etag, size and
          commit_hash.
