+### What it does
+Checks for cases where generics are being used and multiple
+syntax specifications for trait bounds are used simultaneously.
+
+### Why is this bad?
+Duplicate bounds makes the code
+less readable than specifying them only once.
+
+### Example
+```
+fn func<T: Clone + Default>(arg: T) where T: Clone + Default {}
+```
+
+Use instead:
+```
+fn func<T: Clone + Default>(arg: T) {}
+
+// or
+
+fn func<T>(arg: T) where T: Clone + Default {}
+```
+
+```
+fn foo<T: Default + Default>(bar: T) {}
+```
+Use instead:
+```
+fn foo<T: Default>(bar: T) {}
+```
+
+```
+fn foo<T>(bar: T) where T: Default + Default {}
+```
+Use instead:
+```
+fn foo<T>(bar: T) where T: Default {}
