Struct Conjunction 

pub struct Conjunction;

The SQL type of a condition list — a tuple of conditions combined with AND.

Boolean-like, so a condition list is accepted anywhere a condition is, but deliberately not Compatible with itself. A condition list occupies one expression slot rather than one column slot, and self-incompatibility is what lets APIs that accept either a single column or a tuple of columns (IN (subquery) row values) tell the two apart.
