Rust中for循环实质上是一个语法糖,in后面的对象要求是一个迭代器,for循环就是对这个迭代器循环调用next,而in前面的名称就是每一次迭代后返回的结果,如果next返回Option::None则退出循环。了解这一点后我们可以自己编写自己的迭代器类型,然后使用for循环进行迭代。也就是说下面这两种写法可以说是一样的(使用while循环...
所以if/while/for /loop都会返回一个值，函数里的最后一个表达式就是返回值。支持面向接口，泛型。 Go...
Loop:表示一个循环范围,包裹了循环体。 Fn:表示一个函数范围,包裹了函数体。 Ty:表示一个类型范围,包裹了类型定义。 Root:表示根级范围,即不包裹其他内容。 DropRangeVisitor通过遍历AST来收集生成器的控制流信息,构建范围(DropRange)和控制流节点之间的关系。它跟踪生成器或生成器中的控制流信息,并创建DropRange对...

loop、while、for loop:反复执行,直到被 break fn main{ let mut cnt = 0; let result = loop{ cnt += 1; if cnt == 10{ break cnt*2; // 如果 cnt 为10,break 后返回 cnt*2 } }; } 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. while:和其他语言一样 while num != 0{ num = num -...
Rust有三种循环:loop、while和for。for不是C语言风格的for,所以我们将在后面讨论它。while是标准的C语言while循环,语法略有不同。
Imagine that you have a loop with a index array that the compiler can’t easily know that it doesn’t need to bounds check a easy way to ensure that the bounds check will be removed is with the introduction of an assert that will assure to the compiler it is safe. In this case the...
