enum class operators {
  see below;
};
using enum operators;

The enumeration type operators specifies constants used to identify operators that can be overloaded, with the meanings listed in Table 63 .

The values of the constants are distinct.

consteval operators operator_of(info r);

Returns: The value of the enumerator from operators whose corresponding operator-function-id is the unqualified name of the entity represented by r.

Throws: meta::exception unless r represents an operator function or operator function template.

🔗

consteval string_view symbol_of(operators op);
consteval u8string_view u8symbol_of(operators op);

Returns: A string_view or u8string_view containing the characters of the operator symbol name corresponding to op, respectively encoded with the ordinary literal encoding or with UTF-8.

Throws: meta::exception unless the value of op corresponds to one of the enumerators in operators.
