+### What it does
+Checks for usage of `_.find(_).map(_)` that can be written more simply
+as `find_map(_)`.
+
+### Why is this bad?
+Redundant code in the `find` and `map` operations is poor style and
+less performant.
+
+### Example
+```
+(0_i32..10)
+    .find(|n| n.checked_add(1).is_some())
+    .map(|n| n.checked_add(1).unwrap());
+```
+
+Use instead:
+```
+(0_i32..10).find_map(|n| n.checked_add(1));
+```
