Fields

account_cost_limit: u64

block_cost_limit: u64

vote_cost_limit: u64

cost_by_writable_accounts: HashMap<Pubkey, u64>

block_cost: u64

vote_cost: u64

transaction_count: u64

account_data_size: u64

account_data_size_limit: Option<u64>

The amount of total account data size remaining. If Some, then do not add transactions that would cause account_data_size to exceed this limit.
