/// An error will be returned in the following situations:

|
///
|
|
/// * `path` does not point to an existing file or directory.
|
|
/// * The current process lacks permissions to change attributes on the file or directory.
|
|
/// * Some other I/O error occurred.

|
/// # Examples
|
|
///
|
|
/// ```no_run

|
/// # fn main() -> std::io::Result<()> { async_std::task::block_on(async {

/// #

/// use async_std::fs;
