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);

2

#

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

3

#

Throws: meta​::​exception unlessr represents an operator function or operator function template.

🔗

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

4

#

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.

5

#

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