-    /// let mut data = Vec::with_capacity(len);
-    /// r.read_exact(&mut data)?;
+    /// use std::io;
+    /// fn foo<F: io::Read>(mut f: F) {

+    ///     f.read(&mut data).unwrap();

     /// Use instead:
     /// ```rust
-    /// let mut data = Vec::with_capacity(len);
-    /// data.resize(len, 0);
-    /// r.read_exact(&mut data)?;
+    /// use std::io;
