Struct CompactRow 

pub struct CompactRow { /* private fields */ }

Implementations

impl CompactRow

pub fn new(columns: Arc<[String]>, values: Vec<Value>) -> Self

pub fn with_layout(columns: Arc<CompactRowLayout>, values: Vec<Value>) -> Self

pub fn loaded_relation(&self, name: &str) -> Option<&SmartList<CompactRow>>

pub fn set_loaded_relation(&mut self, name: String, list: SmartList<CompactRow>)

pub fn take_loaded_relation( &mut self, name: &str, ) -> Option<SmartList<CompactRow>>

pub fn has_loaded_relations(&self) -> bool

pub fn clear_loaded_relations(&mut self)

Drop read-only relation metadata before retaining a persistence snapshot.

pub fn get(&self, name: &str) -> Option<&Value>

pub fn shared_columns(&self) -> Arc<[String]>

pub fn shared_layout(&self) -> Arc<CompactRowLayout>

pub fn indexed_load_state(&self, layout: Arc<FieldLayout>) -> LoadState

pub fn validate_dynamic_properties(&self) -> Result<(), String>

pub fn attach_dynamic_property_definitions( rows: &mut [Self], definitions: Arc<DynamicPropertyDefinitions>, )

One schema binding per actual result layout, never a dictionary copy per row.

pub fn share_layouts(rows: &mut [Self])

Share actual shapes after relation hydration. The temporary pool cannot retain historical projections, entity values or mutation ownership.

pub fn get_mut(&mut self, name: &str) -> Option<&mut Value>

pub fn insert(&mut self, name: String, value: Value) -> Option<Value>

Adds or replaces a projected value. Column layouts remain shared until an enhancement actually changes the shape of this row.

pub fn remove(&mut self, name: &str) -> Option<Value>

pub fn extend(&mut self, other: CompactRow)

pub fn contains_key(&self, name: &str) -> bool

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn iter(&self) -> impl Iterator<Item = (&String, &Value)>

pub fn keys(&self) -> impl Iterator<Item = &String>

pub fn values(&self) -> impl Iterator<Item = &Value>

pub fn into_map(self) -> BTreeMap<String, Value>

pub fn from_map(values_by_name: BTreeMap<String, Value>) -> Self

Transitional boundary adapter. Core query providers should construct compact rows directly instead of routing through this function.
