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: transform.rs
    path of file: ./repos/swc/bindings/binding_core_node/src
    
    the code of the file until where you have to start completion: use std::{
    path::{Path, PathBuf},
    sync::Arc,
};

use anyhow::Context as _;
use napi::{
    bindgen_prelude::{AbortSignal, AsyncTask, Buffer},
    Env, JsBuffer, JsBufferValue, Ref, Task,
};
use path_clean::clean;
use swc_core::{
    
pub fn transform_sync(s: String, is_module: bool, opts: Buffer) -> napi::Result<TransformOutput> {
    crate::util::init_default_trace_subscriber();

    let c = get_compiler();

    let mut options: Options = get_deserialized(&opts)?;

    if !options.filename.is_empty() {
        options.config.adjust(Path::new(&options.filename));
    }

    let error_format = options.experimental.error_format.unwrap_or_default();

    try_with(
        c.cm.clone(),
        !options.config.error.filename.into_bool(),
        error_format,
        |handler| {
            c.run(|| {
                if is_module {
                    let program: Program =
                        deserialize_json(s.as_str()).context("failed to deserialize Program")?;
                    c.process_js(handler, program, &options)
                } else {
                    let fm = c.cm.new_source_file(
                        if options.filename.is_empty() {
                            FileName::Anon
                        } else {
                            FileName::Real(options.filename.clone().into())
                        },
                        s,
                    );
                    c.process_js_file(fm, handler, &options)
                }
            })
        },
    )
    .convert_err()
}
