Struct Entity

pub struct Entity {
    pub iid: IID,
    pub type_: Option<EntityType>,
}

Instance of data of an entity type, representing a standalone object that exists in the data model independently. Entity does not have a value. It is usually addressed by its ownership over attribute instances and/or roles played in relation instances.

Fields

iid: IID

The unique id of this Entity

type_: Option<EntityType>

The type which this Entity belongs to

Implementations

impl Entity

pub fn iid(&self) -> &IID

Retrieves the unique id of the Entity.

Examples

entity.iid();

pub fn type_(&self) -> Option<&EntityType>

Trait Implementations

impl Clone for Entity

fn clone(&self) -> Entity

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Entity

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

Formats the value using the given formatter.

impl PartialEq for Entity

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