Dspinlock.md13 …msp;DragonOS在`kernel/src/lib/spinlock.rs`文件中，实现了自旋锁。根据功能特性的略微差异，分别提供了`RawSpinLock`和`SpinLock`两种自旋锁。
30 ## 3. SpinLock - 具备守卫的自旋锁
32   `SpinLock`在`RawSpinLock`的基础上，进行了封装，能够在编译期检查出“未加锁就访问临界区的数据”、“忘记放锁”、“双重释放”等问题；并且，支持数据的内部可…
38 pub struct SpinLock<T> {
47 &emsp;&emsp;您可以这样初始化一个SpinLock：
50 let x = SpinLock::new(Vec::new());
53 &emsp;&emsp;在初始化这个SpinLock时，必须把要保护的数据传入SpinLock，由SpinLock进行管理。
55 &emsp;&emsp;当需要读取、修改SpinLock保护的数据时，请先使用SpinLock的`lock()`方法。该方法会返回一个`SpinLockGuard`。您可以使用被保护的数据的成员函数…
60 let x :SpinLock<Vec<i32>>= SpinLock::new(Vec::new());
67 // 在此处，SpinLock是加锁的状态
[all …]
Dlocks.md25 - {ref}`SpinLock <_spinlock_doc_spinlock>` —— 在RawSpinLock的基础上，封装了一层守卫(Guard), 将锁及其要保护到的数据绑定在一个结构体内…
