Struct IndexCatalog 

pub struct IndexCatalog { /* private fields */ }

Implementations

impl IndexCatalog

pub fn list(&self) -> Vec<IndexDefinition>

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

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

pub fn find_equivalent( &self, request: &IndexRequest, ) -> Option<&IndexDefinition>

Look up an existing entry whose (kind, entity, label, properties) match the supplied request. The token-lookup variant collapses to (kind, entity) because there is at most one token index per entity.

pub fn next_auto_name(&mut self, request: &IndexRequest) -> String

Generate a deterministic auto name when the user did not supply one. Names are stable for a given (kind, entity, label, properties) tuple within a session.

pub fn try_create( &mut self, request: IndexRequest, if_not_exists: bool, ) -> Result<CreateIndexOutcome, CreateIndexError>

pub fn try_drop( &mut self, name: &str, if_exists: bool, ) -> Result<DropIndexOutcome, DropIndexError>

pub fn set_state(&mut self, name: &str, state: StoredIndexState)

In-place state transition for an existing entry. Used by lazy-populate flows: an index registers as Populating at CREATE time and flips to Online once the first query triggers the deferred backfill. No-op if the index is gone.
