-### What it does
-Checks for comparing to an empty slice such as `""` or `[]`,
-and suggests using `.is_empty()` where applicable.
-
-### Why is this bad?
-Some structures can answer `.is_empty()` much faster
-than checking for equality. So it is good to get into the habit of using
-`.is_empty()`, and having it is cheap.
-Besides, it makes the intent clearer than a manual comparison in some contexts.
-
-### Example
-
-```
-if s == "" {
-    ..
-}
-
-if arr == [] {
-    ..
-}
-```
-Use instead:
-```
-if s.is_empty() {
-    ..
-}
-
-if arr.is_empty() {
-    ..
-}
-```
