Struct VlsnEntry 

pub struct VlsnEntry {
    pub lsn: u64,
    pub fingerprint: u64,
    pub is_sync: bool,
}

One node’s per-VLSN log identity used for matchpoint comparison: the LSN the entry lives at and a record fingerprint (checksum) used to confirm the two nodes hold the same record at that VLSN, not merely the same VLSN.

JE compares full OutputWireRecord.match(InputWireRecord); here the fingerprint stands in for that record equality.

Fields

lsn: u64

LSN where this VLSN’s log entry resides.

fingerprint: u64

Record fingerprint (e.g. entry checksum) for record-equality.

is_sync: bool

Whether this VLSN is a sync-point (a valid matchpoint candidate). JE only matches at sync points (range.getLastSync() and earlier sync entries scanned by scanMatchpointEntries).

Trait Implementations

impl Clone for VlsnEntry

fn clone(&self) -> VlsnEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for VlsnEntry

impl Debug for VlsnEntry

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

Formats the value using the given formatter.

impl Eq for VlsnEntry

impl PartialEq for VlsnEntry

fn eq(&self, other: &VlsnEntry) -> 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.
