+## `invert_if`
+
+Apply invert_if
+This transforms if expressions of the form `if !x {A} else {B}` into `if x {B} else {A}`
+This also works with `!=`. This assist can only be applied with the cursor
+on `if`.
+
+```rust
+// BEFORE
+fn main() {
+    if┃ !y {A} else {B}
+}
+
+// AFTER
+fn main() {
+    if y {B} else {A}
+}
+```

 ## `make_raw_string`
