使い方(スニペットの登録)
- Visual Stdio Codeを開く。
- メニューバーの ファイル(F)>基本設定 から"ユーザスニペット"をクリック。
- テキスト選択「スニペット ファイルの選択もしくはスニペットの作成」が開く。
- その中から「rust.json（Rust）」を選択。
- 下記のコードをコピー&ペースト。
- ファイルを保存する。
- rust.jsonが自動で読み込まれる。
- rs拡張子ファイルに対して、スニペットが利用できるようになる。
- サジェスト（予測変換）機能から選択し、Tabキーでカーソルが移動する。

##Cargo.toml用のスニペット
- 「toml.json(TOML)」に書き込んで[[bin]]の入力を補完します。
toml.json
