struct not_equal_to;
(since C++20)Function object for performing comparisons. Deduces the parameter types of the function call operator from the arguments (but not the return type).
[edit] Nested types [edit] Member functions checks if the arguments are not equalUnlike std::not_equal_to, std::ranges::not_equal_to requires both == and != to be valid (via the equality_comparable_with constraint), and is entirely defined in terms of std::ranges::equal_to.
The following behavior-changing defect reports were applied retroactively to previously published C++ standards.
