A memory model for Rust code in the kernellwn.net/Articles/967049/ 感兴趣的同学可以去原文了解更多细节并交叉验证我的理解。Rust进入Linux内核已经不是什么新鲜事了,但是在开发实践当中还是一片百废待兴的景象。此处的内存模型并不是说Rust的内存安全保证,而是内存的访问一

Rena是我在Rust中实现的Lox语言的树遍历解释器。我用rust重写它,以熟悉rust的borrow checker和提供的各种工具链。 在这篇文章中,我将解释我如何为解释器实现一个简单的环境。 Gitlab 链接,https:///veera-sivarajan/rena 文章链接,https://veera.app/rena's_memory_model.html yap:一个小型的、基于迭代器的、零...
There's a third hypothetical option of adjusting our concurrency memory model to be able to support these operations. But that's (a) a huge design space -- which fences are supposed to interact how with this? We might even have to add a new kind of fence! And (b) modifying the C++...
详细描述这些模型会占用好几章的篇幅,也超出了本书的范围,但大致上它们可以分为两类:抽象模型(high-level model)和底层模型(low-level model)。抽象模型在思考生存期和借用层面的代码时很有用,而底层模型在推理 Unsafe 代码和 原始指针时很有用。下面两节中描述的变量模型对于本书中大部分内容来说已经足够了。

Rux's goal is to become a safe general-purpose microkernel. It tries to take advantage of Rust's memory model -- ownership and lifetime. While the kernel will be small, unsafe code should be kept minimal. This makes updating functionalities of the kernel hassle-free. ...
Memory safety Speed (Zero cost abstraction) Productivity 显然,Memory safety 和 productivity 是 C++ 开发者的痛点。一门新的系统级语言可以在不失其效率的情况下达到内存安全么?C++ 做了很多探索,创造了不少智能指针,把 RAII(Resource Acquisition Is Initialization)引入语言当中,但由于历史的包袱,使得 C++ 只能在...
