&gt;Rust programs shouldn&#x27;t be parallel to beat a single threaded C++ program.<p>I don&#x27;t write code in either language, but as an outsider my impression is that rust was created to make programming for parallel execution, easier.<p>If that&#x27;s the case, why are we comparing a use case c++ is optimized for against a use case rust isn&#x27;t optimized for?
