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: assimp.rs
    path of file: ./repos/Ambient/crates/model_import/examples
    
    the code of the file until where you have to start completion: use ambient_app::{App, AppBuilder};
use ambient_core::{
    asset_cache,
    camera::{active_camera, far},
    gpu, main_scene,
    transform::*,
};
use ambient_element::ElementComponentExt;
use ambient_model_import::model_crate::ModelCrate;
use ambient_native_std::{asset_u
    
async fn init(app: &mut App) {
    let world = &mut app.world;
    let gpu = world.resource(gpu()).clone();
    let assets = world.resource(asset_cache()).clone();

    Quad.el().with(scale(), Vec3::ONE * 30.).spawn_static(world);

    let model = ModelCrate::local_import(
        &assets,
        &AbsAssetUrl::from_str("https://dims-content.fra1.digitaloceanspaces.com/assets/models/MixamoCharacters/Vanguard By T. Choonyung.fbx")
            .unwrap(),
        true,
        true,
    )
    .await
    .unwrap();

    model.spawn(&gpu, world, &Default::default());

    ambient_cameras::spherical::new(
        vec3(0., 0., 0.),
        SphericalCoords::new(std::f32::consts::PI / 4., std::f32::consts::PI / 4., 5.),
    )
    .with(active_camera(), 0.)
    .with(main_scene(), ())
    .with(far(), 2000.)
    .spawn(world);
}
