Transaction

Struct Transaction 

Source
pub struct Transaction {
    pub transaction_id: u32,
    pub records: Vec<usize>,
    pub lsns: Vec<u64>,
    pub operations: Vec<FileOperation>,
    pub state: TransactionState,
}
Expand description

One terminal-bounded run of $LogFile LFS records within a transaction-table slot — a single logical transaction (one user/OS action) NTFS commits or rolls back as a whole.

transaction_id is the slot the run occupied (the reused open-transaction-table index, LFS header offset 0x24); many Transactions can share one transaction_id. records holds indices into the slice passed to reconstruct_transactions, ascending by LSN (replay order); lsns carries each record’s this_lsn (the run’s LSN set, comparable against an oracle without re-indexing); operations is the parallel FileOperation classification.

Fields§

§transaction_id: u32

The transaction-table slot this run occupied (LFS header offset 0x24). Reused across transactions — not a unique transaction id.

§records: Vec<usize>

Indices into the source record slice, ascending by LSN.

§lsns: Vec<u64>

Each member record’s this_lsn, ascending — the run’s LSN set.

§operations: Vec<FileOperation>

Per-record file-operation classification, parallel to records.

§state: TransactionState

Recovery disposition derived from the terminal / compensation opcode.
