Paths: In Rust, you can use paths to name items in your code. For example, a path can be a data definition like a vector, a code function, or even a module. The module feature also helps you control the privacy of your paths. You can specify the parts of your code that are acces...

如果需要一个vector同时存好几种数据,可以试着把vec和enum结合:1 2 3 4 5 6 7 8 9 10 11 enum SpreadsheetCell { Int(i32), Float(f64), Text(String), } let row = vec![ SpreadsheetCell::Int(3), SpreadsheetCell::Text(String::from("blue")), SpreadsheetCell::Float(10.12), ];...

对同一个对象的不安全读写操作:比如边遍历一个vector边对这个vector做着一些插入删除操作。 C语言的思想是:尽量不对程序员做限制,尽量接近机器底层,类型安全、可变性、共享性都由程序员自由掌控,语言本身不提供太多的限制和规定。安全与否,也完全取决于程序员。所以要写好C代码肯定不会比写好Java简单的。
