Enum FuncBody 

pub enum FuncBody {
    Arithmetic(ArithExpr),
    Conditional(CondExpr),
    Predicate {
        result: String,
        body: Vec<BodyLiteral>,
    },
}

Function body - arithmetic, conditional, or predicate-based

Variants

Arithmetic(ArithExpr)

Pure arithmetic expression: X * X

Conditional(CondExpr)

Conditional expression: if X < 0 then …

Predicate

Predicate-based: P :- parent(X, P)

Fields

result: String

Result variable

body: Vec<BodyLiteral>

Body literals

Trait Implementations

impl Clone for FuncBody

fn clone(&self) -> FuncBody

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FuncBody

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

Formats the value using the given formatter.

impl PartialEq for FuncBody

fn eq(&self, other: &FuncBody) -> 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.
