///
/// # Errors
///
/// An error will be returned in the following situations (not an exhaustive list):
///
/// * `path` does not exist.
/// * The current process lacks permissions to change attributes of `path`.
///
/// # Examples
///
/// ```no_run
/// # fn main() -> std::io::Result<()> { async_std::task::block_on(async {
/// #
/// use async_std::fs;
///
/// let mut perm = fs::metadata("a.txt").await?.permissions();
/// perm.set_readonly(true);
/// fs::set_permissions("a.txt", perm).await?;
/// #
/// # Ok(()) }) }
