我们说明一下:跟第一条规则一样,这条规则违反后,Rust代码不会编译通过。因此就不会有dangling pointer的问题。写的情况下,只有排他引用一个地方可以写,所以不会有data race,包括跨线程的情况(两个引用在不同线程的栈上也可以分析出来)。这样的保证就是Rust自动管理内存下的内存安全性。 Lifetime 这就到了最关键...

StoreBufferAlloc: 这个结构体代表一个存储缓冲区分配,用于在弱内存模型中保存对共享内存的写操作。 StoreBuffer: 这个结构体管理存储缓冲区分配(StoreBufferAlloc),可以向缓冲区中添加写操作,并根据需要将它们提交(commit)到共享内存中。 StoreElement: 这个结构体代表存储缓冲区中的一个元素,包含有关写操作的信息和用...
The most straightforward smart pointer is abox, whose type is writtenBox<T>. Boxes allow you to store data on the heap rather than the stack. What remains on the stack is the pointer to the heap data. Boxes don’t have performance overhead, other than storing their data on the heap ...
-C force-frame-pointers,相当于Clang的-fno-omit-frame-pointer。 -D warnings大致等同于-Werror。 其他有趣的标志可以在rustc -C帮助下找到,在夜间,可以在rustc -Z帮助下找到。
