/// This is an async version of [`std::fs::create_dir`][std]

/// [std]: std::fs::create_dir
///
/// # Platform-specific behavior
///
/// This function currently corresponds to the `mkdir` function on Unix
/// and the `CreateDirectory` function on Windows.
/// Note that, this [may change in the future][changes].
///
/// [changes]: https://doc.rust-lang.org/std/io/index.html#platform-specific-behavior
///
/// **NOTE**: If a parent of the given path doesn't exist, this function will
/// return an error. To create a directory and all its missing parents at the
/// same time, use the [`create_dir_all`] function.
///
/// # Errors
///
/// This function will return an error in the following situations, but is not
/// limited to just these cases:
///
/// * User lacks permissions to create directory at `path`.
/// * A parent of the given path doesn't exist. (To create a directory and all
/// its missing parents at the same time, use the [`create_dir_all`]
/// function.)
/// * `path` already exists.
///
/// [`create_dir_all`]: super::create_dir_all()
///
/// # Examples
///
/// ```no_run
/// use tokio::fs;
/// use std::io;
///
/// #[tokio::main]
/// async fn main() -> io::Result<()> {
/// fs::create_dir("/some/dir").await?;
/// Ok(())
/// }
/// ```
