Struct Invocation

pub struct Invocation { /* private fields */ }

Invocation is a mechanism that permits the evaluation of one value expression – the invoked expression – inside another value expression – the invoking expression – by binding locally the input variables of the invoked expression to values inside the invoking expression.

Implementations

impl Invocation

pub fn called_function(&self) -> &ExpressionInstance

Returns a reference to called function which is an instance of Expression.

pub fn bindings(&self) -> &Vec<Binding>

Returns a reference to the collection of binding instances.

Trait Implementations

impl Clone for Invocation

fn clone(&self) -> Invocation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Invocation

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

Formats the value using the given formatter.

impl DmnElement for Invocation

fn namespace(&self) -> &str

Namespace the element belongs to.

fn id(&self) -> &String

Returns a reference to identifier for this DmnElement. This identifier SHALL be unique within its containing Definitions element.

fn opt_id(&self) -> Option<&String>

Returns a reference to optional identifier for this DmnElement.

fn description(&self) -> &Option<String>

Returns reference to optional description of this DmnElement.

fn label(&self) -> &Option<String>

Returns reference to optional alternative short description of this DmnElement.

fn extension_elements(&self) -> &Vec<ExtensionElement>

Returns reference to attached additional elements to any DmnElement.

fn extension_attributes(&self) -> &Vec<ExtensionAttribute>

Returns reference to attached named extended attributes and model associations to any DmnElement.

impl Expression for Invocation

fn type_ref(&self) -> &Option<String>

Optional namespace-prefixed name of the base type of this Expression.

impl PartialEq for Invocation

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