Note: This policy class specialisation can only be used with basic_result, not basic_outcome. Use error_code_throw_as_system_error<T, EC, EP> with basic_outcome.

Policy class defining that the ADL discovered free function outcome_throw_as_system_error_with_payload(impl.assume_error()) should be called on incorrect wide value observation. Some precanned overloads of that function are listed here.

Incorrect wide error observation performs:

BOOST_OUTCOME_THROW_EXCEPTION(bad_result_access("no error"));

Inherits publicly from base , and its narrow value, error and exception observer policies are inherited from there.

Requires: Nothing.
