一个 C++ 头文件库，让你以简单的几行代码就可以实现高效的并发。示例代码如下： ```c++ #include "taskflow.hpp" // the only include you need int main(){ tf::Taskflow tf(std::thread::hardware_concurrency()); auto [A, B, C, D] = tf.silent_emplace( [] () { std::cout << "TaskA\n"; }, // the taskflow graph [] () { std::cout << "TaskB\n"; }, // [] () { std::cout << "TaskC\n"; }, // +---+ [] () { std::cout << "TaskD\n"; } // +---->| B |-----+ ); // | +---+ | // +---+ +-v-+ A.precede(B); // B runs after A // | A | | D | A.precede(C); // C runs after A // +---+ +-^-+ B.precede(D); // D runs after B // | +---+ | C.precede(D); // D runs after C // +---->| C |-----+ // +---+ tf.wait_for_all(); // block until finished return 0; } ```
