Struct TailRecord 

pub struct TailRecord {
    pub lsn: u64,
    pub term: u64,
    pub payload: Vec<u8>,
}

A single record from the divergent tail that is about to be discarded.

Carries enough to reconstruct the write for an operator who later reconciles a rollback file: its LSN, the term that produced it, and the opaque record payload.

Fields

lsn: u64

LSN of this record on the deposed primary’s local timeline.

term: u64

The replication term under which the deposed primary wrote it.

payload: Vec<u8>

Opaque encoded record bytes, preserved verbatim in the rollback file.

Implementations

impl TailRecord

pub fn new(lsn: u64, term: u64, payload: impl Into<Vec<u8>>) -> TailRecord

Trait Implementations

impl Clone for TailRecord

fn clone(&self) -> TailRecord

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TailRecord

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

Formats the value using the given formatter.

impl Eq for TailRecord

impl PartialEq for TailRecord

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