You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: es2015_destructuring.rs
    path of file: ./repos/swc/crates/swc_ecma_transforms_compat/tests
    
    the code of the file until where you have to start completion: use std::path::PathBuf;

use swc_common::{chain, Mark};
use swc_ecma_parser::Syntax;
use swc_ecma_transforms_base::resolver;
use swc_ecma_transforms_compat::{
    es2015,
    es2015::{
        block_scoping,
        destructuring::{destructuring, Config},
        parameters, spread,
    },
    es2018::object_rest_spread,
};
use swc_ecma_transforms_testing::{test, test_exec, test_fixture};
use swc_ecma_visit::Fold;

fn syntax() -> Syntax {
    Default::default()
}

f
    
fn fixture(input: PathBuf) {
    let parent = input.parent().unwrap();

    let output = parent.join("output.js");
    test_fixture(
        Syntax::Es(Default::default()),
        &|_: &mut swc_ecma_transforms_testing::Tester<'_>| {
            let unresolved_mark = Mark::new();
            let top_level_mark = Mark::new();

            chain!(
                resolver(unresolved_mark, top_level_mark, false),
                object_rest_spread(Default::default()),
                destructuring(Default::default())
            )
        },
        &input,
        &output,
        Default::default(),
    )
}
