Visual Studio Code

  • デバッグ
    • デバッグについて
      • CodeLLDBをインストール
    • デバッグ実行
      • rustのプロジェクトフォルダを開く
      • デバッグ開始（初回）
        • デバッグについて、選択が必要になるため、LLDBを選択する
        • プロジェクト内のCargo.tomlに従って、構成ファイルが作成される
      • デバッグ開始（２回目以降）
        • LLDBを使って、デバッグ実行できる

クレート

  • サンプルWebApp(Actix-Web/SeaORM) Chapter18_WebApp_Search
  • SeaORM
    • テーブルからModel生成 
      sea-orm-cli generate entity -u postgres://postgres:pgsuper@localhost:5432/sample_db -o src/models
  • sqlx for SQLite 
    cargo add sqlx --features "sqlite runtime-tokio chrono"
  • time
    • Rust 1.80 以降は、0.3.35 以上にする必要あり

セッション管理

SSL

  • ローカル認証局のインストール、証明鍵および秘密鍵の作成には、mkcert 1.4.4を利用
    • Chocolatey v2.2.2でインストール
      • Chocolatelyのインストール 
        Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://community.chocolatey.org/install.ps1'))
      • mkcertのインストール 
        choco install mkcert
      • ローカル認証局のインストール 
        mkcert -install
      • 証明鍵、秘密鍵の作成(localhost用) 
        mkcert localhost
  • OpenSSLクレートにより、SSL/HTTP2対応が可能
    • 利用には、vcpkgを使って、OpenSSLのインストールが必要 
      git clone https://github.com/Microsoft/vcpkg.git
cd vcpkg
.\bootstrap-vcpkg.bat
.\vcpkg.exe install openssl:x64-windows-static

$env:OPENSSL_DIR = 'C:\Tools\vcpkg\installed\x64-windows-static'
$env:OPENSSL_STATIC = 'Yes'

Splashscreen

Webページが読み込みに時間がかかったり、メインウィンドウを表示する前に初期処理を実行する必要がある場合、スプラッシュスクリーンによって、ユーザの起動体験を改善できる。

Setup

まず、実行環境のディレクトリにsplashscreen.html（スプラッシュスクリーンのためのHTMLコード）を作る。

  "windows": [
      {
          "title": "Tauri App",
          "width": 800,
          "height": 600,
          "resizable": true,
          "fullscreen": false,
      +   "visible": false // Hide the main window by default
      },
      // Add the splashscreen window
      + {
      +   "width": 400,
      +   "height": 200,
      +   "decorations": false,
      +   "url": "splashscreen.html",
      +   "label": "splashscreen"
      + }
  ]

さて、アプリケーション起動時には、メインウィンドウを非表示にして、スプラッシュスクリーンを表示するようにします。続けて、メインウィンドウが準備できたら、スプラッシュスクリーンを閉じる手段を準備する必要があります。何を待っているかによって、スプラッシュスクリーンを閉じる手段は決まる。

Waiting for Webpage

Webコンテンツを待っているのであれば、フロントエンドからスプラッシュスクリーンを閉じるコマンドを準備したいでしょう。

  use tauri::Manager;
  // Create the command:
  // This command must be async so that it doesn't run on the main thread.
  #[tauri::command]
  async fn close_splashscreen(window: tauri::Window) {
    // Close splashscreen
    if let Some(splashscreen) = window.get_window("splashscreen") {
      splashscreen.close().unwrap();
    }
    // Show main window
    window.get_window("main").unwrap().show().unwrap();
  }

  // Register the command:
  fn main() {
    tauri::Builder::default()
      // Add this line
      .invoke_handler(tauri::generate_handler![close_splashscreen])
      .run(tauri::generate_context!())
      .expect("failed to run app");
  }

２つの方法のうち、いずれかでプロジェクトへインポートできる。

  // With the Tauri API npm package:
  import { invoke } from '@tauri-apps/api/tauri'

または

  // With the Tauri global script:
  const invoke = window.__TAURI__.invoke

最後にイベントリスナに追加する。（または閉じたいときにinvokeを使って呼び出すだけです）:)

  document.addEventListener('DOMContentLoaded', () => {
    // This will wait for the window to load, but you could
    // run this function on whatever trigger you want
    invoke('close_splashscreen')
  })

Waiting for Rust

サーバサイドでのRustコードの実行を待っているのであれば、setup関数ハンドラに置いて、Appインスタンスからアクセスできるようにする。

  use tauri::Manager;
  fn main() {
    tauri::Builder::default()
      .setup(|app| {
        let splashscreen_window = app.get_window("splashscreen").unwrap();
        let main_window = app.get_window("main").unwrap();
        // we perform the initialization code on a new task so the app doesn't freeze
        tauri::async_runtime::spawn(async move {
          // initialize your app here instead of sleeping :)
          println!("Initializing...");
          std::thread::sleep(std::time::Duration::from_secs(2));
          println!("Done initializing.");

          // After it's done, close the splashscreen and display the main window
          splashscreen_window.close().unwrap();
          main_window.show().unwrap();
        });
        Ok(())
      })
      .run(tauri::generate_context!())
      .expect("failed to run app");
  }
