Enum NumericExpr 

pub enum NumericExpr {
    Number(f64),
    FunctionCall(FunctionTerm),
    BinaryOp {
        op: BinaryOp,
        left: Box<NumericExpr>,
        right: Box<NumericExpr>,
    },
    Negate(Box<NumericExpr>),
    TotalTime,
    Duration,
}

A numeric expression tree used in preconditions, effects, durations, and metrics.

N-ary PDDL operators like (+ a b c) are desugared into nested binary operations during parsing, e.g. (+ (+ a b) c).

Variants

Number(f64)

A numeric literal (e.g. 3.14, 0, 100).

FunctionCall(FunctionTerm)

A reference to a numeric fluent (e.g. (distance ?x ?y)).

BinaryOp

A binary arithmetic operation.

Fields

op: BinaryOp

left: Box<NumericExpr>

right: Box<NumericExpr>

Negate(Box<NumericExpr>)

Unary negation (e.g. (- expr)).

TotalTime

The built-in total-time expression (plan makespan).

Duration

The ?duration variable inside durative action constraints.

Trait Implementations

impl Clone for NumericExpr

fn clone(&self) -> NumericExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NumericExpr

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

Formats the value using the given formatter.

impl PartialEq for NumericExpr

fn eq(&self, other: &NumericExpr) -> 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 Serialize for NumericExpr

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
