Struct CheckpointRecord 

pub struct CheckpointRecord { /* private fields */ }

Represents a checkpoint record in the index build process. The checkpoint record can be marked as in-valid to indicate that the exising intermediate data should be discarded. This can happen because of a crash or an unexpected shutdown during the in-memory index build.

Implementations

impl CheckpointRecord

pub fn new() -> CheckpointRecord
