Wraps objects of the DBIDriver class to include connection options. The purpose of this class is to store both the driver and the connection options. A database connection can be established with a call to dbConnect(), passing only that object without additional arguments.


To prevent leakage of passwords and other credentials, this class supports delayed evaluation. All arguments can optionally be a function (callable without arguments). In such a case, the function is evaluated transparently when connecting in dbGetConnectArgs().
