Implementations

impl OptimizedQueryEngine

pub fn new( pool: &NodePool, config: QueryCacheConfig, ) -> Result<OptimizedQueryEngine, Error>

pub fn by_type(&self, node_type: &str) -> Vec<Arc<Node>>

按类型查询（使用索引）

pub fn by_depth(&self, depth: usize) -> Vec<Arc<Node>>

按深度查询（使用索引）

pub fn by_mark(&self, mark_type: &str) -> Vec<Arc<Node>>

按标记查询（使用索引）

pub fn query( &mut self, conditions: Vec<Box<dyn Fn(&Node) -> bool + Sync + Send>>, ) -> Vec<Arc<Node>>

组合查询（使用索引和缓存）
