Struct CommitMarkerRecord 

pub struct CommitMarkerRecord {
    pub commit_seq: u64,
    pub commit_time_unix_ns: u64,
    pub capsule_object_id: [u8; 16],
    pub proof_object_id: [u8; 16],
    pub prev_marker_id: [u8; 16],
    pub marker_id: [u8; 16],
}

On-disk commit marker record.

Layout (88 bytes, all LE):

  commit_seq          : u64      (8)
  commit_time_unix_ns : u64      (8)
  capsule_object_id   : [u8;16]  (16)
  proof_object_id     : [u8;16]  (16)
  prev_marker_id      : [u8;16]  (16) — 0 for genesis
  marker_id           : [u8;16]  (16)
  record_xxh3         : u64      (8)

Fields

commit_seq: u64

Monotonic commit sequence number (gap-free within a segment).

commit_time_unix_ns: u64

Commit timestamp in nanoseconds since Unix epoch.

capsule_object_id: [u8; 16]

ObjectId of the commit capsule.

proof_object_id: [u8; 16]

ObjectId of the proof object.

prev_marker_id: [u8; 16]

marker_id of the previous commit (all zeros for genesis).

marker_id: [u8; 16]

This record’s marker_id: Trunc128(BLAKE3("fsqlite:marker:v1" || prefix_bytes)).

Implementations

impl CommitMarkerRecord

pub fn new( commit_seq: u64, commit_time_unix_ns: u64, capsule_object_id: [u8; 16], proof_object_id: [u8; 16], prev_marker_id: [u8; 16], ) -> Self

Create a new record, computing marker_id from the other fields.

pub fn encode(&self) -> [u8; 88]

Encode to exactly COMMIT_MARKER_RECORD_BYTES bytes.

pub fn decode(data: &[u8]) -> Result<Self, MarkerError>

Decode from a byte slice. Validates xxh3 checksum.

pub fn verify_marker_id(&self) -> bool

Verify that marker_id matches the recomputed value.

Trait Implementations

impl Clone for CommitMarkerRecord

fn clone(&self) -> CommitMarkerRecord

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CommitMarkerRecord

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for CommitMarkerRecord

impl PartialEq for CommitMarkerRecord

fn eq(&self, other: &CommitMarkerRecord) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
