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: loader.rs
    path of file: ./repos/rspack/crates/node_binding/src/plugins
    
    the code of the file until where you have to start completion: use std::{fmt::Debug, path::Path, sync::Arc};

use rspack_binding_options::{get_builtin_loader, JsLoaderAdapter, JsLoaderRunner};
use rspack_core::{
  BoxLoader, CompilerOptions, NormalModule, Plugin, ResolveResult, Resolver, BUILTIN_LOADER_PREFIX,
};
use rspack_error::{error, Result};

pub struct JsLoaderResolver {
  pub js_loader_runner: JsLoaderRunner,
}

impl Debug for JsLoaderResolver {
  fn fmt(&self, f: &mut std::fmt::Formatter<'_>) -> std::fmt::Result {
    f.debu
    
  async fn before_loaders(&self, module: &mut NormalModule) -> Result<()> {
    let contains_inline = module.contains_inline_loader();
    let contains_js_loader = module
      .loaders()
      .iter()
      .any(|l| !l.identifier().starts_with(BUILTIN_LOADER_PREFIX));

    // If there's any JS loader, then we switch to the JS loader runner.
    // Else, we run loader on the Rust side using the Rust loader runner.
    // Note: If the loaders list contains inline loaders,
    // fallback to JS loader runner for passing builtin options(reuse `Compiler.ruleSet`).
    if contains_inline || contains_js_loader {
      *module.loaders_mut_vec() = vec![Arc::new(JsLoaderAdapter {
        runner: self.js_loader_runner.clone(),
        identifier: module
          .loaders()
          .iter()
          .map(|l| l.identifier().as_str())
          .collect::<Vec<_>>()
          .join("$")
          .into(),
      })];
    }

    Ok(())
  }
