Enum Additive 

pub enum Additive {
    Add(Box<Additive>, Multiplicative),
    Subtract(Box<Additive>, Multiplicative),
    Primary(Box<Primary>),
}

Additive expression AST node.

Represents + / - over multiplicative terms or a flattened primary node.

• Add: left + right.
• Subtract: left - right.
• Primary: wrapped lower-precedence expression.

Variants

Add(Box<Additive>, Multiplicative)

Subtract(Box<Additive>, Multiplicative)

Primary(Box<Primary>)

Primary flattened AST optimization

Implementations

impl Additive

pub fn print(&self, writer: &mut Writer)

Trait Implementations

impl Clone for Additive

fn clone(&self) -> Additive

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Additive

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Additive

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl ExpressionLike for Additive

fn to_formula(&self) -> String

Return the formula-string representation (round-trippable by the parser).

fn evaluate(&self, context: &mut dyn ContextLike) -> Result<Arc<Value>>

Evaluate this expression with the provided ContextLike, returning a Value or error.

impl PartialEq for Additive

fn eq(&self, other: &Additive) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl WriterLike for Additive

fn write(&self, writer: &mut Writer)

Serialize this expression with the given Writer.

fn to_stringized(&self) -> String

Return a string representation (raw unsafe output).

fn to_sanitized(&self) -> String

Return a sanitized string representation (escaped for safe output).

fn to_expressionized(&self) -> String

Return a sanitized string representation (escaped for safe output).
