在Rust 中使用内联汇编 (Inline assembly) 自Rust 1.59 以降,在 Rust 代码中内联汇编代码的语言特性已然 stable[1][2]。参考知乎上一篇文章[3],我用 Rust 的内联汇编实现了有栈协程[4]。在此过程中学到了一些知识。 本文假设读者对 x86 汇编有基础了解。 局部内联汇编与自动分配寄存器 Rust 的内联汇编一开始...
Today, the stable Rust compiler supports inline assembly on the following architectures: x86 and x86-64 ARM AArch64 RISC-V You can see more examples of inline assembly in Rust By Example, and find more detailed documentation in the reference. Destructuring assignments You can now use tuple, ...
这是直接驱动面向用户的功能的语言级别限制。 另外,在编写Xous的过程中,像内联汇编(inline assembly)和工作空间(workspaces)这样的东西终于成熟了,这意味着我们需要回到过去,重新审视我们所做的一些“危险”的事情,使那些关键的几行用汇编编写的初始启动代码能够集成到我们的构建系统中。 我经常问自己“我们什么时候才能...
内联汇编(inline assembly) 原始指针 原始指针(raw pointer,裸指针)* 和引用 &T 有类似的功能,但引用总是安全的,因为借用检查器保证了它指向一个有效的数据。解引用一个裸指针只能通过不安全代码块执行。 fn main() { let raw_p: *const u32 = &10; unsafe { assert!(*raw_p == 10); } } 调用不...
The generated function uses inline assembly to define a place for the static-key machinery to patch in a call to the C tracepoint when necessary.她的解决方案是一个小的 Rust 宏,它在 Rust 端创建必要的静态密钥机制。Rust 代码使用 declare_trace!() 来引用在 C 语言中定义的跟踪点;该宏在 Rust...
The example uses the free public MQTT server provided by EMQX for testing connections. The server access information is as follows: Broker:broker.emqx.ioTCP Port:1883Websocket Port:8083 Create a Rust project: $cargo new mqtt-rust-exampleCreated binary (application) `mqtt-rust-example` package ...
Rust to assembly: Arrays, Tuples, Box, and Option handling We have already seen how Rust handles enums under the hood. We also looked at the code generation for the Box smart pointer. Here, we put these items together in a Rust example that describes how arrays, tuples, Option enum, ...
