8/// This is the async equivalent of `std::fs::read_to_string`.

10/// # Examples
11///
12/// ```no_run
13/// use tokio::fs;
14///
15/// # async fn dox() -> std::io::Result<()> {
16/// let contents = fs::read_to_string("foo.txt").await?;
17/// println!("foo.txt contains {} bytes", contents.len());
18/// # Ok(())
19/// # }
20/// ```
