- [#parsing_error_message]
- [section Parsing error message]
- A ['parsing error message] is a
- [link metaprogramming_value template metaprogramming value] with a
- `static std::string get_value()` member function. This function returns the
- pretty-printed version of the error the class represents. For example:
- struct example_error
- {
- using type = example_error;
-
- static std::string get_value()
- {
- return "This is a formatted example error."
- }
- };
- Failing [link parser parser]s return parsing error messages as error messages.
