Struct ResourceObjects 

pub struct ResourceObjects { /* private fields */ }

The resource objects one run’s rules reach: the answers to every class their applicability selectors name, per source.

The runtime installs it before any rule runs, replacing any host copy; capabilities read it through ResourceObjects::reached. Capability tests build one with ResourceObjects::with_class.

Implementations

impl ResourceObjects

pub fn new() -> Self

No resource objects.

pub fn with_class( self, source: SourceId, class: impl Into<String>, include_subtypes: bool, answer: Result<Vec<Object>, String>, ) -> Self

Records the answer for class (as a selector writes it) in source: its resource objects, or why they could not be listed.

pub fn is_empty(&self) -> bool

Whether no class was answered at all.

pub fn object(&self, id: &ObjectId) -> Option<&Object>

The resource object id, if a class listed it.

pub fn reached<'s>( &'s self, selector: &Selector, outcomes: Option<&RuleOutcomes>, ) -> Reached<'s>

The resource objects selector reaches, and the sources where it reaches a class that could not be listed.

An entityType selector reaches its class’s resource objects; allOf and anyOf reach what any operand reaches; a ruleOutcome selector reaches the resource objects the named rule’s outcomes name. Nothing else reaches a resource object: not all, not a negation, not a related or property selector alone. A reached object is selected only when the whole selector then matches it.
