Enum modus_lib::modusfile::Expression

source · [−]

pub enum Expression {
    Literal(Literal<ModusTerm>),
    OperatorApplication(Option<SpannedPosition>, Box<Expression>, Operator),
    And(Option<SpannedPosition>, bool, Box<Expression>, Box<Expression>),

Expand description

Represents expressions that could be found in the body of a ModusClause. Each enum variant will have some notion of span and whether it’s negated. False would mean it is negated.

Variants

`OperatorApplication(Option<SpannedPosition>, Box<Expression>, Operator)`

`And(Option<SpannedPosition>, bool, Box<Expression>, Box<Expression>)`

`Or(Option<SpannedPosition>, bool, Box<Expression>, Box<Expression>)`

Implementations

source

pub fn negate_current(&self) -> Expression

Negates at the current expression level. So, does not apply De Morgan’s laws.
