在Rust编译器源代码中,rustc_builtin_macros/src/compile_error.rs文件是一个实现了compile_error!宏的文件。该宏用于在编译时触发一个错误消息,从而导致编译失败。 具体来说,该文件定义了一个compile_error函数,该函数接受一个字符串作为参数,该字符串将被作为编译错误的错误消息。函数内部使用另一个宏concat!将传...
//cmd.remove(0); //V.push(codeV); //Compile error V.push(None); //OK } //V } fn main() { parse("m {abcd} l {efgh}"); } regex的捕获是指为了提高效率而匹配的字符串。这意味着它们不能超过该字符串,因为匹配组本质上只是该字符串的偏移量。 因为匹配的字符串是在循环体中创建的,这...

在Rust编译器源代码的rustc_span/src/fatal_error.rs文件中,定义了FatalError和FatalErrorMarker这两个结构体。这个文件的作用是定义了在编译器遇到致命错误时使用的错误类型以及相关的工具。 FatalError结构体是一个表示致命错误的类型。它被用于在编译过程中遇到无法恢复的错误时进行报告。这个结构体实现了Debug、Displ...
-D warnings大致等同于-Werror。 其他有趣的标志可以在rustc -C帮助下找到,在夜间,可以在rustc -Z帮助下找到。 Part I: 用 Rust 重写 C 程序 在 深入研究 Rust 的具体特性前,我们将首先探讨 C 语言的概念如何映射到 Rust 中,以及 Unsafe Rust。Unsafe Rust 是Rust 的方言,虽然没有 Safe Rust 的太多限制...
