Rust の Deref と DerefMut で継承ができると思わない

Rust でオレオレ文字列型を定義して既存コードに散りばめられた String を置き換えたい気持ちになることがあります。

単純に API を追加して事足りる場合、必要な API をトレイトで定義した上で String に実装すれば十分です:

trait PushNewLine {
    fn push_newline(&mut self);
}

1. Update Cargo.toml and Cargo.lock

For example, 1.0.0 -> 1.0.1,

-version = "1.0.0"
+version = "1.0.1"

2. Push the commit to the master branch
