| /// @assertion Future<Link> rename(String newPath) |
| /// Renames this link. |
| /// |
| /// Returns a `Future<Link>` that completes with a [Link] for the renamed link. |
| /// |
| /// If [newPath] identifies an existing file or link, that entity is removed |
| /// first. If [newPath] identifies an existing directory then the future |
| /// completes with a [FileSystemException]. |
| /// |
| /// @note Shortly: |
| /// - [File]/[Link] `rename/renameSync` can replace other [File]/[Link] but not |
| /// [Directory] |
| /// - [Directory] `rename/renameSync` can not replace an existing |
| /// [File]/[Link]/[Directory] except on POSIX where it can replace an empty |
| /// [Directory] |
| /// In order to create a symbolic link on Windows, Dart must be run in |
| /// Administrator mode or the system must have Developer Mode enabled, otherwise |
| /// a [FileSystemException] will be raised with `ERROR_PRIVILEGE_NOT_HELD` set |
| /// as the errno when this call is made. |
| /// |
| /// @description Checks that if [newPath] identifies an existing directory, the |
| /// operation fails and the future completes with an exception. The link being |
| /// renamed is a link to a directory |
