因此,C++11推出了std::function与std::bind这两件大杀器,他们配合起来能够很好的替代函数指针。

DR应用于出版时的行为正确行为 LWG 2101C++11曾要求std::add_pointer产生指向 cv 或引用限定的函数类型的指针。产生 cv 或引用限定的函数类型自身。 参阅 is_pointer (C++11) 检查类型是否为指针类型 (类模板) remove_pointer (C++11) 移除给定类型的一层指针 (类模板)...
Rust pointer.wrapping_add用法及代码示例 本文简要介绍rust语言中pointer.wrapping_add的用法。 用法 pubfnwrapping_add(self, count:usize) -> *constT 使用环绕算法计算指针的偏移量。 (方便.wrapping_offset(count as isize)) count以T为单位;例如,count为 3 表示3 * size_of::<T>()字节的指针偏移量。
