<!-- library, but without it you must define your own. -->
今のところ、コンパイラは実行可能形式においていくつかのシンボルが呼び出し可能であるという前提を置いています。通常、これらの関数は標準ライブラリが提供しますが、それを使わない場合自分で定義しなければなりません。

2つある関数のうち1つ目は `eh_personality` で、コンパイラの失敗メカニズムに使われます。これはしばしばGCCのpersonality関数に割り当てられますが（詳細は[libstd実装](../std/rt/unwind/index.html)を参照してください）、パニックを発生させないクレートではこの関数は呼ばれないことが保証されています。2つ目の関数は `panic_fmt` で、こちらもコンパイラの失敗メカニズムのために使われます。

こちらですが、

Circle CI で生成された HTML を見ると、リンクがうまく生成されていないようです。原文のように、unwind の周りのカッコを [ ] に変更してください。
