pub struct WorkingMemory { /* private fields */ }

Working Memory - stores and manages facts (Drools-style)

Implementations

impl WorkingMemory

pub fn new() -> Self

Create a new empty working memory

pub fn insert(&mut self, fact_type: String, data: TypedFacts) -> FactHandle

Insert a fact into working memory (returns FactHandle)

pub fn update( &mut self, handle: FactHandle, data: TypedFacts, ) -> Result<(), String>

Update a fact in working memory

pub fn retract(&mut self, handle: FactHandle) -> Result<(), String>

Retract (delete) a fact from working memory

pub fn get(&self, handle: &FactHandle) -> Option<&WorkingMemoryFact>

Get a fact by handle

pub fn get_by_type(&self, fact_type: &str) -> Vec<&WorkingMemoryFact>

Get all facts of a specific type

pub fn get_all_facts(&self) -> Vec<&WorkingMemoryFact>

Get all facts

pub fn get_all_handles(&self) -> Vec<FactHandle>

Get all fact handles

pub fn get_modified_handles(&self) -> &HashSet<FactHandle>

Get modified handles since last clear

pub fn get_retracted_handles(&self) -> &HashSet<FactHandle>

Get retracted handles since last clear

pub fn clear_modification_tracking(&mut self)

Clear modification tracking (after propagation)

pub fn stats(&self) -> WorkingMemoryStats

Get statistics

pub fn clear(&mut self)

Clear all facts

pub fn to_typed_facts(&self) -> TypedFacts
