Hi all, thanks to Vladimir and Valerii for their previous detailed answer to my email, now i have a more general question.
My Connection struct has a "new" method with open a connection to a database. This connection can fails. Three possiblities : 1/ "new" returns an IoResult<Connection>. The connection must be unwrapped from the IoResult before using it 2/ "new" returns a "Connection"; after the instantiation, a test must be made using a method like "getIoResult -> Option<IoResult>" 3/ any other way to do ???? For me, the 1/ is the best one, the connection can not be used until it is returned by new. With 2/, the test can be forgotten. Any suggestion ?
