/// @assertion Future<Directory> rename(String newPath)
/// Renames this directory. Returns a Future<Directory> that completes with a
/// Directory instance for the renamed directory.
///
/// If [newPath] identifies an existing directory, then the behavior is
/// platform-specific. On all platforms, a [FileSystemException] is thrown
/// if the existing directory is not empty. On POSIX systems, if [newPath]
/// identifies an existing empty directory then that directory is deleted
/// before this directory is renamed.
///
/// If newPath identifies an existing file the operation fails and a
/// [FileSystemException] is thrown.
///
/// @description Checks that if newPath identifies an existing file, the
/// operation fails and the future completes with an exception.
