高级函数/闭包:函数指针(function pointer)和返回闭包(return closures)。 宏(macro): 一种定义代码的方法,这些方法会在编译的时候定义更多的代码(ways to define code that defines more code at compile time)。 unsafe Rust[2] 目前我们代码都是基于内存安全的,并且会在编译阶段进行限制报错不安全代码。 不过ru...
println!("{}, world!", s1); // Won't compile. The value of s1 has already been dropped. 左右滑动查看完整代码 在将s1分配给s2之后(在let s2 = s1赋值语句中),s1的值就被释放了。因此,赋值语句执行后,s1就失效了。s1被释放后的内存状态: 图11:s1被释放后的内存状态 9.所有权如何变动 在Rust...
一旦我们解开了y的引用,就可以访问y指向的整型数据,然后将其与5进行比较。 如果我们尝试写assert_eq!(5, y);就会得到以下编译错误提示: 复制 error[E0277]: can't compare `{integer}` with `&{integer}` --> src/main.rs:11:5 | 11 | assert_eq!(5, y); | ^^^ no implementation for `{inte...

3.Compile与Runtime Rust支持静态、动态链接。 Runtime时程序结构封闭。但由于标准库的元编程功能强大,即便是对比Java这种Runtime灵活的语言也不会落多少下风。 4.命名规范 C语言风格,类似Go,越简单越好。我认为语言上偏简单的设计,则对工程师的能力要求更强。
只要认真看完这篇文章就会发现,该文其实是标题党,他们应该只是想寻求帮助,并不是真的想放弃 Rust,他只是放弃了用 Rust 开发游戏,Rust游戏引擎应该还会维护。 文章作者罗列了 Rust 在游戏开发领域的局限性,这对 Rust 语言技术选型有很大参考意义。 作者强调,对于技术热情没有错,但认为人们应该非常谨慎地考虑自己的实...
