-### What it does
-Checks for the use of `.extend(s.chars())` where s is a
-`&str` or `String`.
-
-### Why is this bad?
-`.push_str(s)` is clearer
-
-### Example
-```
-let abc = "abc";
-let def = String::from("def");
-let mut s = String::new();
-s.extend(abc.chars());
-s.extend(def.chars());
-```
-The correct use would be:
-```
-let abc = "abc";
-let def = String::from("def");
-let mut s = String::new();
-s.push_str(abc);
-s.push_str(&def);
-```
