std::align_val_t 定义于头文件<new> enumclassalign_val_t:std::size_t{}; (C++17 起) 在将new 表达式和delete 表达式用于对齐要求大于__STDCPP_DEFAULT_NEW_ALIGNMENT__的对象时,该对齐要求作为std::align_val_t类型的参数传递给分配/解分配函数。
std::align_val_t Defined in header<new> enumclassalign_val_t:std::size_t{}; (since C++17) Bothnew-expressionanddelete-expression, when used with objects whose alignment requirement is greater than__STDCPP_DEFAULT_NEW_ALIGNMENT__, pass that alignment requirement as an argument of typestd::...

where T: ?Sized, 🔬This is a nightly-only experimental API. (layout_for_ptr #69835) 返回val 指向的值类型的 ABI 要求的最小对齐方式 (以字节为单位)。 T 类型的值的每个引用必须是该数字的倍数。 Safety 仅在满足以下条件时,此函数才可以安全调用: 如果T 是Sized,则调用该函数始终是安全的。
