结构体 (struct),Rust 与 golang 语言类似没有提供class关键词。同样提供了struct,但是在rust中通过结构体 (struct) 和 trait(trait)来实现面向对象的特性。 与c++/c不一样的地方是: Rust引入了所有权系统和借用检查器,以确保内存安全和避免数据竞争。这导致Rust在编写面向对象代码时需要更多的注意事项,例如处理生...

【Rust每周一知】Rust 中新的切片模式 对于Rust v1.42.0中的高级切片模式(advanced slice patterns),开发者Thomas Hartmann写了一篇博客文章,总结了我们会从中得到什么以及为什么他认为这很重要。本文是我对原文的翻译,同时增加了一些示例。 关于切片模式(slice patterns) 一直以来,在稳定版Rust上我们已使用了某些形式...
