} RustLogMessage;voidrust_log(structRustLogMessage msg); 3、新建C语言代码并编译 3.1 新建C语言代码, mymain.c: #include <stdio.h>#include<stdlib.h>#include"rust_log.h" // include header fileintmain() {for(inti =0; i <10; i++) { RustLogMessage msg={ id : i, msg :"string in C...
C++中多数函数和方法都需要声明两次:一次在 header 里,一次在实现文件里。但 Rust 不需要,因此代码行数会更少 C++的完整构建时间比 Rust 长(Rust 更胜一筹)。在每个.cpp 文件里,都需要重新编译一次 C++的#include功能和模板,虽然都是并行运行,但并行不等于完美。 Rust 的增量构建时间比 C++长(C++更胜一筹)。
接下来,CMake需要在Rust crate的include文件夹中查找头文件: SET(LIB_HEADER_FOLDER"${CMAKE_CURRENT_SOURCE_DIR}/rust_lib/include")set_target_properties(rust_libPROPERTIESIMPORTED_LOCATION${LIB_FILE}INTERFACE_INCLUDE_DIRECTORIES${LIB_HEADER_FOLDER}) 将Rust字符串传递到C的五种方式 一切准备就绪。下面,我...
