default_policy<T, EC, EP>
A type alias to a no-value policy selected based on traits matching of T, EC and EP. It is defined as follows:
- If - ECand- EPis- void, choose- terminate.
- If - is_error_code_available<T>true for- EC, choose- error_code_throw_as_system_error<T, EC, EP>for- basic_outcomeor- error_code_throw_as_system_error<T, EC, void>for- basic_result.
- If - is_exception_ptr_available<T>true for- ECor- EP, choose- exception_ptr_rethrow<T, EC, EP>for- basic_outcomeor- exception_ptr_rethrow<T, EC, void>for- basic_result.
- Else choose - fail_to_compile_observers, which fails the build with a useful message.
