Rust 0.11.0リリース

MozillaとRustコミュニティは、新しいRustリリースであるバージョン0.11.0をリリースしました。



言語は開発の活発な段階にあるという事実にもかかわらず、作業は型システムとライブラリの改善に焦点を合わせました。 主な作業は、動的サイズ（DST）を使用した型の実装と標準ライブラリのリファクタリングで行われました。

このリリースでは、BoxおよびGcタイプのために〜および@も標準ライブラリから削除されました（コンパイラはこれまで必要以上にこれらのタイプを知っていますが、まもなくこれらのタイプはRustの最も一般的なタイプになります）。

DST、ベクトルおよび文字列

動的なサイズの型（DST）を導入する準備として、 ~str ~[T]
