std::experimental::ranges::equal_to

Header: <experimental/ranges/functional>

Function object for performing comparisons. The primary template invokes operator == on const lvalues of type T. The specialization equal_to deduces the parameter types of the function call operator from the arguments (but not the return type).

# Declarations

template< class T = void >
requires EqualityComparable<T> ||
Same<T, void> ||
/* == on two const T lvalues invokes a built-in operator comparing pointers */
struct equal_to;

(ranges TS)

template<>
struct equal_to<void>;

(ranges TS)

# Notes

Unlike std::equal_to, ranges::equal_to requires both == and != to be valid (via the EqualityComparable and EqualityComparableWith constraints).
