定义于头文件 <experimental/filesystem>
class directory_entry;		(filesystem TS)

表示目录项。此对象存储一个 path 和两个 file_status 对象：一个用于文件状态，第二个用于被指向文件的状态（如果目录项引用符号链接）。

成员函数

(构造函数)	构造目录项 (public member function)
(析构函数)	默认析构函数 (public member function)
修改器
operator=	赋值内容 (public member function)
assign	赋值内容 (public member function)
replace_filename	设置文件名 (public member function)
观察器
pathoperator const path&	返回条目所指路径 (public member function)
statussymlink_status	由此目录项指定文件的缓存状态 由此目录项指定文件的缓存符号链接状态 (public member function)
operator==operator!=operator<operator<=operator>operator>=	比较两个目录项 (public member function)
