empty_record_type_named_fields_list

The list of named fields in a record type can't be empty.

The analyzer produces this diagnostic when a record type has an empty list of named fields.

The following code produces this diagnostic because the record type has an empty list of named fields:

void f((int, int, {}) r) {}

If the record is intended to have named fields, then add the types and names of the fields:

void f((int, int, {int z}) r) {}

If the record isn't intended to have named fields, then remove the curly braces:

void f((int, int) r) {}
