有没有办法访问Bevy中的摄像头缓冲区？

use bevy::prelude::*;
use bevy::render::camera::Camera;
use bevy::render::texture::Texture;

fn main() {
    App::build()
        .add_plugins(DefaultPlugins)
        .add_plugin(bevy::window::WindowPlugin::default())
        .add_plugin(bevy::input::InputPlugin::default())
        .add_plugin(bevy::asset::AssetPlugin::default())
        .add_plugin(bevy::transform::TransformPlugin::default())
        .add_plugin(bevy::render::RenderPlugin::default())
        .add_plugin(bevy::sprite::SpritePlugin::default())
        .add_plugin(bevy::camera::CameraPlugin::default())
        .add_plugin(bevy::winit::WinitPlugin::default())
        .add_plugin(bevy::wgpu::WgpuPlugin::default())
        .add_plugin(bevy::diagnostic::FrameTimeDiagnosticsPlugin::default())
        .add_startup_system(setup.system())
        .add_system(update.system())
        .run();
}

fn setup(commands: &mut Commands, mut materials: ResMut<Assets<ColorMaterial>>) {
    commands.spawn_bundle(OrthographicCameraBundle::new_2d());
}

fn update(
    commands: &mut Commands,
    mut texture: ResMut<Assets<Texture>>,
    mut query: Query<(&Camera, &mut Texture)>,
) {
    for (camera, mut texture) in query.iter_mut() {
        // 获取摄像头缓冲区的数据
        let camera_texture = camera.output.as_ref().unwrap();
        let camera_texture_data = texture.get_mut(camera_texture).unwrap().data.as_mut_slice();
        
        // 处理摄像头缓冲区的数据
        // ...
    }
}
