-
-Replaces `let` with an `if-let`.
-
-.Before
-```rust
-
-fn main(action: Action) {
-    ┃let x = compute();
-}
-
-fn compute() -> Option<i32> { None }
-```
-
-.After
-```rust
-
-fn main(action: Action) {
-    if let Some(x) = compute() {
-    }
-}

-
-Adds a use statement for a given fully-qualified name.

-
-Replaces `unwrap` a `match` expression. Works for Result and Option.
-
-.Before
-```rust
-enum Result<T, E> { Ok(T), Err(E) }
-fn main() {
-    let x: Result<i32, i32> = Result::Ok(92);
-    let y = x.┃unwrap();
-}
-```
-
-.After
-```rust
-enum Result<T, E> { Ok(T), Err(E) }
-fn main() {
-    let x: Result<i32, i32> = Result::Ok(92);
-    let y = match x {
-        Ok(a) => a,
-        $0_ => unreachable!(),
-    };
-}

-
-This assist removes if...else, for, while and loop control statements to just keep the body.
-
-.Before
-```rust
-fn foo() {
-    if true {┃
-        println!("foo");
-    }
-}
-```
-
