Input

struct Foo {}
impl Foo {
    fn bar() {}
    fn baz() {
        $0Self::bar();$0
    }
}

Expected output

struct Foo {}
impl Foo {
    fn bar() {}
    fn baz() {
        Self::fun_name();
    }

    fn fun_name() {
        Self::bar();
    }
}

Output

struct Foo {}
impl Foo {
    fn bar() {}
    fn baz() {
        fun_name();
    }
}

fn fun_name() {
    Self::bar();
}

Explanation

fun_name() should be defined inside an impl Foo, preferably the same one it was extracted from, otherwise Self is not defined

Reproduce the extract-function assist with the Rust input shown and locate the extraction implementation and its existing tests. The work is done when extracting a call using Self keeps the new function inside the appropriate impl block and the behavior is covered by a regression test.
