• full: <u64>

  • Represents the highest full snapshot slot
  • A full snapshot contains the complete state of the blockchain at a specific slot

• incremental: <u64|null>

  • Highest incremental snapshot slot based on the full snapshot
  • May be null if no incremental snapshot is available
  • Incremental snapshots only record changes since the last full snapshot
