-    ///* Checks for [push](https://doc.rust-lang.org/std/path/struct.PathBuf.html#method.push)
-    /// calls on `PathBuf` that can cause overwrites.
-    ///
-    /// ### Why is this bad?
-    /// Calling `push` with a root path at the start can overwrite the
-    /// previous defined path.
-    ///
-    /// ### Example
-    /// ```rust
-    /// use std::path::PathBuf;
-    ///
-    /// let mut x = PathBuf::from("/foo");
-    /// x.push("/bar");
-    /// assert_eq!(x, PathBuf::from("/bar"));
-    /// ```
-    /// Could be written:
-    ///
-    /// ```rust
-    /// use std::path::PathBuf;
-    ///
-    /// let mut x = PathBuf::from("/foo");
-    /// x.push("bar");
-    /// assert_eq!(x, PathBuf::from("/foo/bar"));
-    /// ```
