template< typename ExecutionContext, typename NullaryToken = DEFAULT> DEDUCED dispatch( ExecutionContext & ctx, NullaryToken && token = DEFAULT, typename constraint< is_convertible< ExecutionContext &, execution_context & >::value >::type = 0);
An execution context, from which the target executor is obtained.
The completion token that will be used to produce a completion handler. The function signature of the completion handler must be:
