-    /// ### What it does
-    /// Checks for use of File::read_to_end and File::read_to_string.
-    ///
-    /// ### Why is this bad?
-    /// `fs::{read, read_to_string}` provide the same functionality when `buf` is empty with fewer imports and no intermediate values.
-    /// See also: [fs::read docs](https://doc.rust-lang.org/std/fs/fn.read.html), [fs::read_to_string docs](https://doc.rust-lang.org/std/fs/fn.read_to_string.html)
-    ///
-    /// ### Example
-    /// ```rust,no_run
-    /// # use std::io::Read;
-    /// # use std::fs::File;
-    /// let mut f = File::open("foo.txt").unwrap();
-    /// let mut bytes = Vec::new();
-    /// f.read_to_end(&mut bytes).unwrap();
-    /// ```
-    /// Can be written more concisely as
-    /// ```rust,no_run
-    /// # use std::fs;
-    /// let mut bytes = fs::read("foo.txt").unwrap();
-    /// ```
