A factory for database objects.

This trait is to be implemented by descriptors of parameters for database commands.

Example

A parameter descriptor for a String-valued database type might implement all methods with adequate conversions, while a parameter descriptor for an integer type might only support conversions from the rust integer types.

Associated Types

type DBV

The type of the database objects.
