由于Rust中的元组实现了PartialOrd和字典序比较，因此可以使用sort_by_key()方法：
It's easy to compare two collections for equality with an external iterator, for example, but it's practically impossible with internal iterators. Internal iterators are especially weak in a language like C++ that does not provide anonymous functions, closures, or continuations like Smalltalk and ...

T: 'static 既包括所有 &'static T,也包括所有拥有所有权的类型,如 String、Vec 等。只要数据的所有者持有这些数据,就能保证其永不失效,也就是说所有者可以安全地、无限期地持有这些数据,直到程序结束。T: 'static 应被视作 “T 受'static 生命周期约束”,而不是 “T 拥有'static 生命周期”。用程序来...
6 minutes To figure out if a programming language is suitable for your project, you need to know the features and the limitations. Then you can compare the possible languages and choose the one that will work best. In this unit, we'll review some of the features and limitations of Rust:...
