Enum ComparisonOperator

pub enum ComparisonOperator {
    Equal,
    Lower,
    Grater,
    LowerEq,
    GraterEq,
}

Expand description

Provides the available comparison operators for standardizing input for the Conditions.add_condition() method.

The available comparison operators are:

Equal: Represents the equality condition, where the column and the value are chained by “=”
Lower: Represents the less than condition, where the column and the value are chained by “<”
Greater: Represents the greater than condition, where the column and the value are chained by “>”
LowerEq: Represents the less than or equal to condition, where the column and the value are chained by “<=”
GreaterEq: Represents the greater than or equal to condition, where the column and the value are chained by “>=”

Variants§
