WalRecord

Struct WalRecord 

Source
pub struct WalRecord<'a> {
    pub offset: usize,
    pub type_byte: u8,
    pub commit_lsn: Option<u64>,
    pub commit_unix_us: Option<i64>,
    pub sql: &'a [u8],
}
Expand description

v7.18 PITR — parsed WAL record, surfaced for restore / verify tooling. The replay loop above doesn’t expose LSN/timestamp; spgctl restore --to <timestamp> and spgctl verify need them. Returned offsets are byte-positions inside the WAL buffer.

Fields§

§offset: usize

Byte offset in the WAL buffer where this record starts.

§type_byte: u8

Type byte (0x01 = v3 auto-commit, 0x10 = v4 auto-commit, 0x02 = durability checkpoint marker).

§commit_lsn: Option<u64>

Some(lsn) for v4 records, None for v3.

§commit_unix_us: Option<i64>

Some(unix_us) for v4 records carrying a clock-set timestamp, None for v3 or for v4 records explicitly written with WAL_V4_NO_CLOCK (sentinel for “no ClockFn at commit time”).

§sql: &'a [u8]

SQL payload as borrowed bytes. Empty for durability markers.
