文章中包含了相关模块介绍。 管理unsafe代码。 它们在项目根模块添加了#![deny(unsafe_code)] ,但是自己实现了一个unsafe_block!宏: macro_rules!unsafe_block{($reason:tt=>$body:expr)=>{{#[allow(unsafe_code)]letr=unsafe{$body};r}};} 在编写unsafe代码的时候使用这个宏,这就使得不安全的代码更具有...
Unsafe 导致 unsound, unsound 导致 undefined, undefined 是一切原力的阴暗面. Unsafe Code Unsafe 代码 标记为 unsafe 的代码有特权.比如, 解引用裸指针, 或调用其他 unsafe 函数. 这是一份特殊的作者必须给编译器的承诺, 编译器会相信你. unsafe 代码自身并非有害, 但危险的是 FFI 使用方或者异常的数据结构...
rust/src/tools/miri/src/helpers.rs这个文件是Miri(Rust语言的一个模拟执行器)工具的辅助函数和数据结构的定义文件。它包含了一些用于处理unsafe代码和模拟执行的函数和结构体。 具体来说,这个文件中的函数和结构体主要用于Miri对Rust源代码中的unsafe块进行静态分析和模拟执行。以下是文件中几个重要的结构体和trait以...
