这个hello_macro的library放我们的trait。 pub trait HelloMacro { fn hello_macro(); } 然后my_pro包中引入这个trait use hello_macro::HelloMacro; struct Pancakes; impl HelloMacro for Pancakes { fn hello_macro() { println!("Hello, Macro! My name is Pancakes!"); } } fn main() { Pancakes...
gcc -o call_rust call_rust.c libfoo.a -lpthread 提示依然确实dlsym库,我们再将这个库加上: gcc -o call_rust call_rust.c libfoo.a -lpthread -ldl 编译成功,此时会在当前目录下生成call_rust。 执行call_rust,显示: hello : a + b = 12 7、在rust的库函数foo中,我们使用的类型为i32,但有时我...
