Module zebra_state::service::finalized_state::disk_db

source ·
Expand description

Provides low-level access to RocksDB using some database-specific types.

This module makes sure that:

  • all disk writes happen inside a RocksDB transaction ([rocksdb::WriteBatch]), and
  • format-specific invariants are maintained.

§Correctness

crate::constants::state_database_format_version_in_code() must be incremented each time the database format (column, serialization, etc) changes.

Modules§

  • tests 🔒
    Tests and test methods for low-level RocksDB access.

Structs§

  • DiskDb
    Wrapper struct to ensure low-level database access goes through the correct API.
  • DiskWriteBatch
    Wrapper struct to ensure low-level database writes go through the correct API.

Traits§

  • ReadDisk
    Helper trait for retrieving and deserializing values from rocksdb column families.
  • WriteDisk
    Helper trait for inserting serialized typed (Key, Value) pairs into rocksdb.

Type Aliases§

  • DB

  • DBThreadMode
    The [rocksdb::ThreadMode] used by the database.
