std::uses_allocator<std::variant>

STD：：用途[医]分配器<std：：Variable>

template struct uses_allocator, Alloc> : std::true_type { };​(since C++17)

提供std::uses_allocator类型性状std::variant通知其他库组件可以使用分配器构造变体，即使它没有嵌套的allocator_type...

类型要求

*。

-分配器必须符合分配器的要求。

继承自STD：积分[医]常量

成员常数

value statictrue (public static member constant)

成员函数

operator boolconverts the object to bool, returns value (public member function)
operator() (C++14)returns value (public member function)

成员类型

TypeDefinition
value_typebool
typestd::integral_constant<bool, value>

注记

大std::variant它本身不使用分配器，而是传递到包含的值的构造函数。

例

另见

uses_allocator (C++11)checks if the specified type supports uses-allocator construction (class template)
