Struct LogRecord 

pub struct LogRecord {
    pub page_offset: usize,
    pub this_lsn: u64,
    pub client_previous_lsn: u64,
    pub client_undo_next_lsn: u64,
    pub record_type: u32,
    pub transaction_id: u32,
    pub redo_op: LogOp,
    pub undo_op: LogOp,
    pub target_attribute: u16,
    pub mft_cluster_index: u16,
    pub target_vcn: u64,
}

One decoded LFS log record from a $LogFile RCRD page.

Combines the Log File Service record header (this/previous/undo LSNs, record type, transaction id) with the NTFS log-record operation descriptor that forms the record’s client data: the redo/undo LogOp, the target attribute (an index into the Open Attribute Table), and the target VCN.

Fields

page_offset: usize

Byte offset of this record within its RecordPage’s data.

this_lsn: u64

This record’s log sequence number (LFS record header, offset 0x00).

client_previous_lsn: u64

The client’s previous LSN (offset 0x08).

client_undo_next_lsn: u64

The client’s undo-next LSN (offset 0x10).

record_type: u32

LFS record type (offset 0x20): normal log record vs restart/checkpoint.

transaction_id: u32

Transaction identifier (offset 0x24).

redo_op: LogOp

The redo operation (NTFS log-record offset 0x30 — the client data start).

undo_op: LogOp

The undo operation (offset 0x32).

target_attribute: u16

Index into the Open Attribute Table identifying the target (offset 0x3C).

mft_cluster_index: u16

MFT cluster index of the target (offset 0x44).

target_vcn: u64

Target VCN (offset 0x48).
