        engine: &EK, 
        kv_snap: &EK::Snapshot, 
        region: &Region,

Snapshot is a trait for snapshot. It’s used in these scenarios:

  1. build local snapshot
  2. read local snapshot and then replicate it to remote raftstores
  3. receive snapshot from remote raftstore and write it to local storage
  4. apply snapshot
  5. snapshot gc
