-C force-frame-pointers,相当于Clang的-fno-omit-frame-pointer。 -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...
C语言传递参数均是以值传递(pass by value),另外也可以传递指针(a pointer passed by value)。不同的变量类型可以用结构体(struct)组合在一起。只有32个保留字(reserved keywords),使变量、函数命名有更多弹性。部分的变量类型可以转换,例如整型和字符型变量。通过指针(pointer),C语言可以容易的对内存进行低级控制...
