#[non_exhaustive]
pub enum Expression {
    Equals {

        rhs: Value,
    },
    NotEquals {
        lhs: Value,
        rhs: Value,
    },
    And {
        lhs: Box<Expression>,
        rhs: Box<Expression>,
    },
    Or {
        lhs: Box<Expression>,
        rhs: Box<Expression>,
    },
}

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
