std::exception_ptr current_exception() noexcept; (C++11 起) 若在当前异常处理(典型地在 catch 子句中)中调用,则捕获当前异常对象,并创建一个保有该异常对象复制或到该异常对象引用的 std::exception_ptr (依赖于实现)。被引用对象保持合法,只要至少要有一个 exception_ptr 对象引用它。

与现代C或C ++编译器相比,likely/unlikely支持/可能性似乎弱得多。(https://doc.rust-lang.org/std/intrinsics/fn.unlikely.html) 在Rust中可以从原始内存读写数据结构,但是比C甚至C ++需要更多的代码。不过没什么大不了的。(https://users.rust-lang.org/t/reading-structures-in-memory-via-pointers/33886)...
