文件rust/compiler/rustc_passes/src/naked_functions.rs的主要作用是为Rust编译器的各个阶段提供对裸函数(naked functions)的检查和处理。裸函数是指没有函数调用规范(calling convention)和修饰(prologue/epilogue)的函数,通常用于与汇编语言进行交互。 在这个文件中,CheckPa
We use the mut keyword before the variable name to create a mutable variable. For example, let mut x = 1; Here, x is a mutable variable. Now we can change the value of x. Example: Mutable Variables fn main() { // declare a mutable variable with value 1 let mut x = 1; println...

When I made my first contribution to the main miri code base, I was for a brief moment (slightly) confused about the variables this and ecx, mostly used to store the result of eval_context_{ref,mut}. It would be nice if the name was consistent. I see that this is most commonly ...

When working with low-level protocols it's common to encounter variable-length structures consisting of a fixed header followed by a blob of payload bytes. The header contains enough info to identify the layout of the payload, which can then be parsed with content-specific logic. ...
