Detailed Description

Holds string context, error_code and the pointer to the following error.

This is extension over std::error_code, to make it possible to identify the context of the error (usually it is actor identity), and make it possible to construct the chain of failures, that's why there is a smart pointer to the next error.

std::string rotor::extended_error_t::message ( const message_stringifier_t *  stringifier = nullptr ) const

noexcept

human-readable detailed description of the error

First, it stringifies own error in accordance with the context.

Second, it recursively ask details on all following errors, appending them into the result. The result string is returned.
