Implementations§

Source§

impl ViewIndex

Source

pub fn new() -> Self

Source

pub fn set_entity_scope(&mut self, export: impl Into<String>, field: ScopeField)

Scope an entity’s rows by field (row scoping, see crate::row_scope): every view of the entity, derived views included, then delivers a row only to sessions whose row scopes cover it, and its sorted views keep their rows per scope.

Call while building the index, before it is shared.

Source

pub fn set_max_scope_partitions(&mut self, max_partitions: usize)

Cap the scope partitions each sorted view of a scoped entity keeps (default DEFAULT_MAX_SCOPE_PARTITIONS). See SortedViewCache::partition_by_scope.

Source

pub fn max_scope_partitions(&self) -> usize

Source

pub fn scope_field_for_view(&self, view_id: &str) -> Option<&ScopeField>

The scope field governing a view’s rows: its entity’s, for the view or any view it derives from. None for views of unscoped entities.

Source

pub fn has_scoped_entities(&self) -> bool

Whether any entity is row-scoped.

Source

pub fn add_spec(&mut self, spec: ViewSpec)

Source

pub fn by_export(&self, entity: &str) -> &[ViewSpec]

Source

pub fn get_view(&self, id: &str) -> Option<&ViewSpec>

Source

pub fn get_derived_views(&self) -> Vec<&ViewSpec>

Source

pub fn get_derived_views_for_source( &self, source_view_id: &str, ) -> Vec<&ViewSpec>

Source

pub fn sorted_caches(&self) -> Arc<RwLock<HashMap<String, SortedViewCache>>> ⓘ

Source

pub async fn init_sorted_cache( &self, view_id: &str, sort_field: Vec<String>, order: SortOrder, )
