Struct HotIndex 

pub struct HotIndex { /* private fields */ }

分片热层索引 —— 将ID哈希路由到对应分片，减少全局锁竞争

Implementations

impl HotIndex

pub fn new(cfg: &HotConfig) -> Result<Self>

pub fn add_sync(&self, id: String, vec: Vec<f32>) -> Result<()>

pub async fn write_batch( &self, items: Vec<(String, Vec<f32>)>, trace_id: String, ) -> Result<()>

异步批量写入（经由背景协程，避免阻塞调用方）

pub fn remove(&self, id: &str) -> Option<Vec<f32>>

pub fn get(&self, id: &str) -> Option<Vec<f32>>

pub fn touch(&self, id: &str)

pub fn contains(&self, id: &str) -> bool

pub fn len(&self) -> usize

pub fn search(&self, query: &[f32], k: usize) -> Result<Vec<(String, f32)>>

跨分片搜索，合并后取top-k

pub fn collect_evictions(&self) -> Vec<String>

返回所有超出容量被驱逐的ID（由波动引擎处理后续迁移）
