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: asset_processing.rs
    path of file: ./repos/bevy/examples/asset/processing
    
    the code of the file until where you have to start completion: //! This example illustrates how to define custom `AssetLoader`s, `AssetTransformer`s, and `AssetSaver`s, how to configure them, and how to register asset processors.

use bevy::{
    asset::{
        embedded_asset,
        io::{Reader, Writer},
        processor::LoadTransformAndSave,
    
fn setup(mut commands: Commands, assets: Res<AssetServer>) {
    // This the final processed versions of `assets/a.cool.ron` and `assets/foo.c.cool.ron`
    // Check out their counterparts in `imported_assets` to see what the outputs look like.
    commands.insert_resource(TextAssets {
        a: assets.load("a.cool.ron"),
        b: assets.load("foo/b.cool.ron"),
        c: assets.load("foo/c.cool.ron"),
        d: assets.load("d.cool.ron"),
        e: assets.load("embedded://asset_processing/e.txt"),
    });
