Module solana_runtime::snapshot_utils

Structs

• BankFromArchiveTimings
• BankSnapshotInfo
  Information about a bank snapshot. Namely the slot of the bank, the path to the snapshot, and the type of the snapshot.

Enums

• ArchiveFormat
  The different archive formats used for snapshots
• BankSnapshotType
  Bank snapshots traditionally had their accounts hash calculated prior to serialization. Since the hash calculation takes a long time, an optimization has been put in to offload the accounts hash calculation. The bank serialization format has not changed, so we need another way to identify if a bank snapshot contains the calculated accounts hash or not.
• ParseError
• SnapshotError
• SnapshotVersion
• VerifyBank
  allow tests to specify what happened to the serialized format
• VerifySlotDeltasError
  Errors that can happen in verify_slot_deltas()

Functions

• add_bank_snapshot
  Serialize a bank to a snapshot
• archive_snapshot_package
  Make a snapshot archive out of the snapshot package
• bank_fields_from_snapshot_archives
  Utility for parsing out bank specific information from a snapshot archive. This utility can be used to parse out bank specific information like the leader schedule, epoch schedule, etc.
• bank_from_latest_snapshot_archives
  Rebuild bank from snapshot archives. This function searches full_snapshot_archives_dir and incremental_snapshot_archives_dir for the highest full snapshot and highest corresponding incremental snapshot, then rebuilds the bank.
• bank_from_snapshot_archives
  Rebuild bank from snapshot archives. Handles either just a full snapshot, or both a full snapshot and an incremental snapshot.
• bank_to_full_snapshot_archive
  Convenience function to create a full snapshot archive out of any Bank, regardless of state. The Bank will be frozen during the process. This is only called from ledger-tool or tests. Warping is a special case as well.
• bank_to_incremental_snapshot_archive
  Convenience function to create an incremental snapshot archive out of any Bank, regardless of state. The Bank will be frozen during the process. This is only called from ledger-tool or tests. Warping is a special case as well.
• build_full_snapshot_archive_path
  Build the full snapshot archive path from its components: the snapshot archives directory, the snapshot slot, the accounts hash, and the archive format.
• build_incremental_snapshot_archive_path
  Build the incremental snapshot archive path from its components: the snapshot archives directory, the snapshot base slot, the snapshot slot, the accounts hash, and the archive format.
• build_snapshot_archives_remote_dir
• deserialize_snapshot_data_file
• get_bank_snapshots
  Get the bank snapshots in a directory
• get_bank_snapshots_post
  Get the bank snapshots in a directory
• get_bank_snapshots_pre
  Get the bank snapshots in a directory
• get_full_snapshot_archives
  Get a list of the full snapshot archives from a directory
• get_highest_bank_snapshot_post
  Get the bank snapshot with the highest slot in a directory
• get_highest_bank_snapshot_pre
  Get the bank snapshot with the highest slot in a directory
• get_highest_full_snapshot_archive_info
  Get the path (and metadata) for the full snapshot archive with the highest slot in a directory
• get_highest_full_snapshot_archive_slot
  Get the highest slot of the full snapshot archives in a directory
• get_highest_incremental_snapshot_archive_info
  Get the path for the incremental snapshot archive with the highest slot, for a given full snapshot slot, in a directory
• get_highest_incremental_snapshot_archive_slot
  Get the highest slot of the incremental snapshot archives in a directory, for a given full snapshot slot
• get_incremental_snapshot_archives
  Get a list of the incremental snapshot archives from a directory
• package_and_archive_full_snapshot
  Helper function to hold shared code to package, process, and archive full snapshots
• package_and_archive_incremental_snapshot
  Helper function to hold shared code to package, process, and archive incremental snapshots
• path_to_file_name_str
  Get the &str from a &Path
• purge_old_bank_snapshots
  Remove outdated bank snapshots
• purge_old_snapshot_archives
• remove_bank_snapshot
  Remove the snapshot directory for this slot
• remove_tmp_snapshot_archives
  If the validator halts in the middle of archive_snapshot_package(), the temporary staging directory won’t be cleaned up. Call this function to clean them up.
• serialize_snapshot_data_file
• should_take_full_snapshot
• should_take_incremental_snapshot
• snapshot_bank
  Gather the necessary elements for a snapshot of the given root_bank.
• verify_snapshot_archive
