,可以通过以下步骤实现: 1. 创建一个空字符串变量,用于存储转换后的结果。 2. 遍历vector<char>中的每个元素,将其逐个追加到字符串变量中。 3. 在追加完所有元素后,将字符串变量返回...

char*c=const_cast<char*>(str.c_str()); std::cout<<c; return0; } 下载运行代码 输出: std::string to char* 2.使用strcpy()功能 在这里,想法是通过const char*由返回string::c_str或者string::data的功能strcpy()函数,它在内部将其复制到指定的字符数组中并返回一个指针。

My FFI binding returns a struct with fixed-size c_char arrays, and I would like to turn those into std::ffi::CString or std::String. It looks like the CString::new function coerces the pointer to a vector. use std::ffi::CString; use std::os::raw::c_char; #[repr(C)] pub st...
