+### What it does
+
+Checks for iterating a map (`HashMap` or `BTreeMap`) and
+ignoring either the keys or values.
+
+### Why is this bad?
+
+Readability. There are `keys` and `values` methods that
+can be used to express that we only need the keys or the values.
+
+### Example
+
+```
+let map: HashMap<u32, u32> = HashMap::new();
+let values = map.iter().map(|(_, value)| value).collect::<Vec<_>>();
+```
+
+Use instead:
+```
+let map: HashMap<u32, u32> = HashMap::new();
+let values = map.values().collect::<Vec<_>>();
+```
