-/// This function will return an error in the following situations, but is not
-/// limited to just these cases:
-///
-/// * If any directory in the path specified by `path`
-/// does not already exist and it could not be created otherwise. The specific
-/// error conditions for when a directory is being created (after it is
-/// determined to not exist) are outlined by [`fs::create_dir`].
+/// The function will return an error if any directory specified in path does not exist and
+/// could not be created. There may be other error conditions; see [`fs::create_dir`] for specifics.
 ///
 /// Notable exception is made for situations where any of the directories
 /// specified in the `path` could not be created as it was being created concurrently.
