变量说明

construct

template<typename T >

constexpr construct_t<T> elc::defs::memory::lifetime_n::construct {}

constexpr

constexpr变量模板，用于构造实例 用法： construct<类型>.able<构造参数类型> -> bool construct<类型>.nothrow<构造参数类型> -> bool construct<T>(参数) -> T （以参数构建T类型实例）

construct<T>[T*ptr](参数) -> T* （以参数在ptr地址处构建T类型实例，返回ptr） construct<T>[T*ptr][size_t size](参数) -> T* （以参数在ptr地址处构建size个T类型实例，返回ptr）
