+### What it does
+Checks for no-op uses of `Option::{as_deref, as_deref_mut}`,
+for example, `Option<&T>::as_deref()` returns the same type.
+
+### Why is this bad?
+Redundant code and improving readability.
+
+### Example
+```
+let a = Some(&1);
+let b = a.as_deref(); // goes from Option<&i32> to Option<&i32>
+```
+
+Use instead:
+```
+let a = Some(&1);
+let b = a;
+```
