std::strong_ordering operator<=>(const directory_entry& rhs )constnoexcept;	(7)	(since C++20)

Compares the path with the directory entry rhs.

The <, <=, >, >=, and != operators are synthesized from operator<=> and operator== respectively.

(since C++20)

Parameters

rhs

-

directory_entry to compare

Return value

1)true if path()== rhs.path(), false otherwise.

2)true if path()!= rhs.path(), false otherwise.

3)true if path()< rhs.path(), false otherwise.

4)true if path()<= rhs.path(), false otherwise.

5)true if path()> rhs.path(), false otherwise.

6)true if path()>= rhs.path(), false otherwise.

7) The result of path()<=> rhs.path().
