6/// Creates a new directory.
7///
8/// Note that this function will only create the final directory in `path`. If you want to create
9/// all of its missing parent directories too, use the [`create_dir_all`] function instead.
10///
11/// This function is an async version of [`std::fs::create_dir`].
12///

15///
16/// # Errors
17///
18/// An error will be returned in the following situations:
19///
20/// * `path` already points to an existing file or directory.
21/// * A parent directory in `path` does not exist.
22/// * The current process lacks permissions to create the directory.
23/// * Some other I/O error occurred.
24///
25/// # Examples
26///
27/// ```no_run
28/// # fn main() -> std::io::Result<()> { async_std::task::block_on(async {
29/// #
30/// use async_std::fs;
31///
32/// fs::create_dir("./some/directory").await?;
33/// #
34/// # Ok(()) }) }
35/// ```
