Implementations

pub fn iid(&self) -> &IID

Trait Implementations

impl Clone for Thing

fn clone(&self) -> Thing

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Thing

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

Formats the value using the given formatter.

impl PartialEq for Thing

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

impl ThingAPI for Thing

fn iid(&self) -> &IID

Retrieves the unique id of the Thing.

fn is_inferred(&self) -> bool

Checks if this Thing is inferred by a [Reasoning Rule].

fn to_thing_cloned(&self) -> Thing

fn is_deleted<'tx>( &self, transaction: &'tx Transaction<'_>, ) -> BoxPromise<'tx, Result<bool>>

Checks if this Thing is deleted.

fn delete<'tx>( &self, transaction: &'tx Transaction<'_>, ) -> BoxPromise<'tx, Result>

Deletes this Thing.

fn get_has<'tx>( &self, transaction: &'tx Transaction<'_>, attribute_types: Vec<AttributeType>, annotations: Vec<Annotation>, ) -> Result<BoxStream<'tx, Result<Attribute>>>

Retrieves the Attributes that this Thing owns. Optionally, filtered by an AttributeType or a list of AttributeTypes. Optionally, filtered by Annotations.

fn set_has<'tx>( &self, transaction: &'tx Transaction<'_>, attribute: Attribute, ) -> BoxPromise<'tx, Result>

Assigns an Attribute to be owned by this Thing.

fn unset_has<'tx>( &self, transaction: &'tx Transaction<'_>, attribute: Attribute, ) -> BoxPromise<'tx, Result>

Unassigns an Attribute from this Thing.

fn get_relations<'tx>( &self, transaction: &'tx Transaction<'_>, role_types: Vec<RoleType>, ) -> Result<BoxStream<'tx, Result<Relation>>>

Retrieves all the Relations which this Thing plays a role in, optionally filtered by one or more given roles.
