Struct EntityRoot 

pub struct EntityRoot { /* private fields */ }

Implementations

impl EntityRoot

pub fn push_change_set(&self)

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

pub fn clear_current_change_set(&self)

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)

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

pub fn is_new(&self) -> bool

Check if this entity root is marked as newly created.

pub fn set_original_record(&self, record: Record)

Store the original record when loaded from DB.

pub fn original_record(&self) -> Option<Record>

Retrieve the original record.

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().

Trait Implementations

impl Clone for EntityRoot

fn clone(&self) -> EntityRoot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EntityRoot

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

Formats the value using the given formatter.

impl Default for EntityRoot

fn default() -> EntityRoot

Returns the “default value” for a type.

impl PartialEq for EntityRoot

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