Struct Relation

pub struct Relation { /* private fields */ }

A Relation is convenient a shorthand for a list of similar contexts.

A Relation has a column instead of repeated ContextEntrys, and a List is used for every row, with one of the List’s expression for each column value.

Implementations

impl Relation

pub fn rows(&self) -> &Vec<List>

Returns a reference to collection of relation’s rows.

pub fn columns(&self) -> &Vec<InformationItem>

Returns a reference to collection of relation’s columns.

Trait Implementations

impl Clone for Relation

fn clone(&self) -> Relation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Relation

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

Formats the value using the given formatter.

impl DmnElement for Relation

fn namespace(&self) -> &str

Namespace the element belongs to.

fn model_name(&self) -> &str

Name of the model the element was defined in.

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 Relation

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

Returns a reference to optional type definition.

impl PartialEq for Relation

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