The singleton pattern has many applications in software development, such as a database connection pool, a globally unique dialog, a global logging tool, and more.

Rust 编译器错误信息所建议的修复方法可以使程序编译成功,但这并不等同于可以使程序编译成功并且最符合要求。 生命周期在编译期进行静态验证 生命周期不能在运行期以任何方式增长、缩短或改变 Rust 借用检查器总是假定所有代码路径都会被执行,然后为变量选择最短的生命周期 ...
Convex的创始团队(从DropBox分离出来的)有使用Rust开发Magic Pocket(Dropbox的地理分布式数据存储系统),Nucleus(重写的Dropbox的同步引擎),Convex(0配置,无限扩容的为响应式应用开发需求设计的后端)。它们是目前世界上负载最大的基于Rust语言的系统之一。 Convex的创始团队分享了使用Rust的好处和一些取舍心得体会。十分推荐...
