Rust 1.80 稳定了LazyCell和LazyLock。借助这两个新类型,开发人员可以将数据的初始化延迟到第一次访问时。该版本提供了对开区间的支持以及一些相关的 lint 警告。为了与 C23 兼容,该版本允许使用不带命名参数的可变函数。此外,它还稳定了许多 API。 LazyCell和LazyLock可以延迟共享数据的初始化,其中LazyLock是线程安...

大家好,又见面了,我是你们的朋友全栈君。 涉及到并行/并发计算时,通常都会想到加锁,加锁可以保护共享的数据,不过也会存在一些问题: 1. 由于临界区无法并发运行,进入临界区就需要等待,加锁使得效率的降低。多核CPU也不能发挥全部马力 2. 在复杂的情况下,很容易造成死锁,并发进程、线程之间无止境的互相等待。

And this is basically how many interior mutability primitives in Rust work, whether it's anRwLock,Mutex, orRefCell. The problem with our implementation ofget_nameis that it tries to take a lock and then borrow a value through the lock. However, when we exit theget_namemethod it's still...
