它展示了一些核心数据类型、结构和trait的定义和实现,以及它们在编译器代码生成器中的使用。 现在让我们来详细介绍一下PhantomData, Global, NonNull, Unique, Box, ManuallyDrop, VaList<'a>(&'a, PanicLocation这几个 struct 的作用: PhantomData:它是一个零大小的类型,用于在泛型代码中向编译器传达关于类型参数...
如果我们用Box<Node<T>>来代替,看看有什么不同,这可能是个好主意。 我们讨论了什么是Unique<T>以及它与NonNull<T>有何不同,但作为一个快速提醒,Unique<T>拥有 referent 而NonNull<T>没有, 实际上,Box<T>(用于堆分配的指针类型) 包装了Unique<T>提供了与Unique<T>交互的新的接口。 让我们考虑Node<T>使...
enumList{Cons(i32,Box<List>),Nil,}use List::{Cons,Nil};fnmain(){letlist=Cons(1,Box::new(Cons(2,Box::new(Cons(3,Box::new(Nil)));// 使用 `Box` 解决递归类型} 在上述示例中,我们定义了一个递归类型List,表示一个整数链表。通过使用Box,我们可以在Cons变体中包装一个指向下一个节点的Box<...
Sized>(ptr:Unique<T>){letptr=ptr.as_ptr();letsize=size_of_val(&*ptr);letalign=min_align_of_val(&*ptr);// We do not allocate for Box<T> when T is ZST, so deallocation is also not necessary.ifsize!=0{letlayout=Layout::from_size_align_unchecked(size,align);dealloc(ptras*mut ...
