Member Data Documentation
!NULL - This KeyUse was created from an equality that was wrapped into an Item_func_trig_cond. This means the equality (and validity of this KeyUse element) can be turned on and off. The on/off state is indicted by the pointed value: *cond_guard == true <=> equality condition is on *cond_guard == false <=> equality condition is off
NULL - Otherwise (the source equality can't be turned off)

If true, the comparison this value was created from will not be satisfied if val has NULL 'value'.
