Struct IVFRecordHeader

pub struct IVFRecordHeader {
    pub dimensions: u32,
    pub params: IVFIndexParams,
    pub state: IVFState,
    pub trained_size: usize,
    pub deletes_since_train: usize,
    pub vector_count: usize,
    pub revision: Option<u64>,
}

Fields§

§dimensions: u32§params: IVFIndexParams§state: IVFState§trained_size: usize§deletes_since_train: usize§vector_count: usize§revision: Option<u64>

Optional persisted mutation counter; native layouts without that column rely on record revisions and input validation.
