struct MyType {
    foo: usize,
}
impl MyType {
    fn print_foo(&self) {
        println!("{}", self.foo);
    }
}

It would be nice to be able to filter for MyType::print_foo, but currently it seems this is not possible.

What does syn say the type of the print_foo declaration is?

The impl block has the type Item::Impl and the associated function is ImplItem::Fn.

The complete (debug) output is:
