Enum FunctionBody 

pub enum FunctionBody {
    Conditional(Arc<Evaluator>),
    Context(Arc<Evaluator>),
    DecisionService(Arc<Evaluator>),
    DecisionTable(Arc<Evaluator>),
    Every(Arc<Evaluator>),

}

Function body may be defined multiple ways using FEEL or DMN. This enum is the representation of all of these cases.

Variants

Conditional(Arc<Evaluator>)

Function body created from boxed conditional (if) expression defined in DMN model.

Context(Arc<Evaluator>)

Function body created from context defined in DMN model.

DecisionService(Arc<Evaluator>)

Function body created from decision service defined in DMN model.

DecisionTable(Arc<Evaluator>)

Function body created from decision table defined in DMN model.

Every(Arc<Evaluator>)

Function body created from boxed every expression defined in DMN model.

External(Arc<Evaluator>)

Function body created from externally defined function in Java or PMML.

Filter(Arc<Evaluator>)

Function body created from boxed filter expression defined in DMN model.

For(Arc<Evaluator>)

Function body created from boxed for loop defined in DMN model.

FunctionDefinition(Arc<Evaluator>)

Function body created from function definition defined in DMN model.

Invocation(Arc<Evaluator>)

Function body created from invocation defined in DMN model.

List(Arc<Evaluator>)

Function body created from list defined in DMN model.

LiteralExpression(Arc<Evaluator>)

Function body created from FEEL textual expression defined in DMN model.

Relation(Arc<Evaluator>)

Function body created from relation defined in DMN model.

Some(Arc<Evaluator>)

Function body created from boxed some expression defined in DMN model.

Implementations

impl FunctionBody

pub fn evaluate(&self, scope: &FeelScope) -> Value

Evaluates function body, takes a FeelScope as input and returns evaluated Value.

Trait Implementations

impl Clone for FunctionBody

fn clone(&self) -> FunctionBody

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FunctionBody

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

Formats the value using the given formatter.

impl PartialEq for FunctionBody

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