Struct EntityRoot 

pub struct EntityRoot { /* private fields */ }

Implementations

impl EntityRoot

pub fn with_shared_graph(&self, source: &EntityRoot) -> Self

Make this root resolve entities from the same flat graph as source. Existing snapshots and mutation ledger state remain owned by this root.

pub fn freeze_graph( &self, builder: EntityGraphBuilder, ) -> Result<(), EntityGraphBuilder>

Publish a completely assembled graph. It becomes immutable after this call.

pub fn resolve_entity<T>(&self, id: u64) -> Option<&T>

where T: Any + Send + Sync,

Resolve an entity by type and ID without locking or reference cloning.

pub fn resolve_relation_list<T>( &self, owner_entity: &str, owner_id: u64, relation: &str, ) -> Option<&SmartList<T>>

where T: Any + Send + Sync,

pub fn resolve_relation_option<T>( &self, owner_entity: &str, owner_id: u64, relation: &str, ) -> Option<&Option<T>>

where T: Any + Send + Sync,

pub fn has_relation_view( &self, owner_entity: &str, owner_id: u64, relation: &str, ) -> bool

pub fn push_change_set(&self)

pub fn pop_change_set(&self) -> Option<EntityChangeSet>

pub fn clear_current_change_set(&self)

pub fn clear_committed(&self)

Clear all state consumed by a successfully committed ledger save. Failed saves must not call this method so their pending intent remains retryable.

pub fn set( &self, key: EntityKey, field: impl Into<String>, value: impl Into<Value>, )

pub fn get(&self, key: &EntityKey, field: &str) -> Option<Value>

pub fn current_change_set(&self) -> EntityChangeSet

pub fn set_comment(&self, comment: impl Into<String>)

Set an annotation comment on this entity root. The comment propagates through the graph save process for observability.

pub fn get_comment(&self) -> Option<String>

Get the annotation comment, if any.

pub fn mark_as_new(&self, key: EntityKey)

Mark this entity root as a newly created entity in memory.

pub fn is_new(&self, key: &EntityKey) -> bool

Check if this entity root is marked as newly created.

pub fn set_original_snapshot(&self, snapshot: EntitySnapshot)

Store an original loaded entity snapshot.

pub fn set_original_compact_row(&self, row: CompactRow)

Store a shared-schema snapshot without eagerly allocating a map.

pub fn original_snapshot(&self) -> Option<EntitySnapshot>

Retrieve the original loaded entity snapshot.

pub fn mark_as_delete(&self, key: EntityKey)

Mark an entity as deleted. The next save() call will treat this entity as a Remove operation in the graph save pipeline. Any pending field changes for this entity are cleared — they are irrelevant when the entity is being deleted.

pub fn is_marked_as_delete(&self, key: &EntityKey) -> bool

Check whether an entity has been marked for deletion.

pub fn changed_field_names(&self, key: &EntityKey) -> BTreeSet<String>

Get the set of field names that have been modified for the given entity key. This is the Rust equivalent of Java’s entity.getUpdatedProperties().

pub fn deleted_keys(&self) -> BTreeSet<EntityKey>

pub fn new_keys(&self) -> BTreeSet<EntityKey>

pub fn get_original_version(&self, key: &EntityKey) -> Option<i64>

pub fn get_trace_chain(&self, key: &EntityKey) -> Vec<TraceNode>

pub fn set_original_version(&self, key: EntityKey, version: i64)
