Module bal 

Block Access List (BAL) data structures for efficient state access in blockchain execution.

This module provides types for managing Block Access Lists, which optimize state access by pre-computing and organizing data that will be accessed during block execution.

Key Types

• BlockAccessIndex: block access index
• BalAccountInfo: account fields a BAL changed, each None when not written
• BalAccountLookup: complete, partial, or uncovered account information at a read position
• Bal: Main BAL structure containing a map of accounts
• BalWrites<T>: Array of (index, value) pairs representing sequential writes to a state item
• AccountBal: Complete BAL structure for an account (balance, nonce, code, and storage)
• AccountInfoBal: Account info BAL data (nonce, balance, code)
• StorageBal: Storage-level BAL data for an account
