pub enum Operator {
Eq,
NotEq,
Gt,
Gte,
Lt,
Lte,
And,
Or,
Add,
}Expand description
Equalities, inequalities, and boolean operations over possibly null values.
For the equalities and inequalities, if either side is null, the result is null. The Boolean operators obey Kleene (three-valued) logic.
Variants§
Eq
NotEq
Gt
Gte
Lt
Lte
And
Or
Add
The sum of the arguments.
Errs at runtime if the sum would overflow or underflow.
The result is null at any index that either input is null.
