Public Attributes
LogicalIndex	index
	The indexed column of the constraint. Only used for single-column constraints, invalid otherwise.
vector< string >	columns
	The names of the columns on which this constraint is defined. Only set if the index field is not set.
bool	is_primary_key
	Whether this is a PRIMARY KEY constraint, or a UNIQUE constraint.
