+    /// ### Example
+    ///
+    /// ```
+    /// fn bytes_at_home(x: [u8; 4]) -> u32 {

+    /// ## Explanation
+    ///
+    /// People dont realize that safer methods such as [`u32::to_ne_bytes`] exist,
+    /// so this lint exists to lint on cases where people write transmutes that dont need to be there.
