わかりました。Rust の Cargo ワークスペースを使って learning-wgpu と wasmsample2 という 2 つのプロジェクトを作成する手順を説明します。以下の手順に従ってプロジェクトを設定しましょう。
- まず、新しいディレクトリを作成し、そこに移動します:
mkdir rust-wgpu-workspace
cd rust-wgpu-workspace- このディレクトリに
Cargo.tomlファイルを作成し、ワークスペースを定義します:
touch Cargo.tomlCargo.tomlファイルを編集し、以下の内容を追加します:
[workspace]
members = [
"learning-wgpu",
"wasmsample2"
]- 次に、各プロジェクトのディレクトリを作成します:
cargo new learning-wgpu
cargo new wasmsample2- 各プロジェクトの
Cargo.tomlファイルを編集して、必要な依存関係を追加します。例えば、learning-wgpu/Cargo.tomlに wgpu の依存関係を追加する場合:
[dependencies]
wgpu = "0.18"- 同様に、
wasmsample2/Cargo.tomlに必要な依存関係を追加します。
これで、基本的なワークスペースの構造が整いました。各プロジェクトのソースコードは、それぞれのディレクトリの src フォルダ内に配置されます。
プロジェクト全体をビルドする場合は、ルートディレクトリで以下のコマンドを実行します:
cargo build特定のプロジェクトのみをビルドする場合は、以下のようにします:
cargo build -p learning-wgpuまたは
cargo build -p wasmsample2これで、Cargo ワークスペースを使用して learning-wgpu と wasmsample2 プロジェクトを作成できました。各プロジェクトの実装を進めることができます。
追加の情報や特定の実装に関する質問がありましたら、お知らせください。
https://doc.rust-jp.rs/book-ja/ch14-03-cargo-workspaces.html TRPL が一番わかりやすい
mkdir して手動で Cargo.toml を作ってディレクトリ入ってその下で cargo new add-one --lib して使う側のほうの Cargo.toml を手動で dependencies を書いて import する
その後 extern crate で持ってきて呼び出す

windows のハンドラーのライブラリらしい。
winit は windows 上の window だけじゃなくて chrome 上の canvas とかモバイル OS も統一的に扱える

バリアントとフィールドの違い
理解。バリアントはenumのフィールドだがその実態は埋め込み構造体のようなもの。enumで埋め込み構造体を表現する
https://qiita.com/etoilevi/items/4bd4c5b726e41f5a6689
rlibがrustから利用されるlib cdylibがffiされるlib dylibとcdylibがある。dylibはもちろん動的ライブラリ。で静的ライブラリもある。
rlibはrust static library
libを作るときにはlib.rsという名前にする必要がある、もしくはlibセクションの中でpathを指定してあげる必要がある
別ファイルから呼び出すときはmodを忘れないように
cfg-if・・・マクロをつき足す。unixのみ動作するとかができるようになる
wasm-bindgen-futuresはwasm-bindgenのpromiseとjsのpromiseをつなぐ https://crates.io/crates/wasm-bindgen-futures
console_log・・・jsのconsole.log apiに送る
console_error_panic_hook・・・rustのpanicにhookしてpanicの内容をjsのconsole.logに送る
web-sys・・・web-apiをwasm-bindgenにbindする https://crates.io/crates/web-sys
