Struct HistoryEntry 

pub struct HistoryEntry {
    pub seq: u64,
    pub ts: i64,
    pub op: LogOp,
    pub partition: String,
    pub offset: u64,
    pub length: u64,
    pub document: Option<HaysonRecord>,
}

One log line naming a record, as Table::history read it off the file — the version itself, not the record as the live schema would project it.

Fields

seq: u64

ts: i64

op: LogOp

partition: String

The partition file this line was found in — UNPARTITIONED on a table with no partitionBy, and on one whose declared split has not run yet.

offset: u64

length: u64

document: Option<HaysonRecord>

The record exactly as the line stores it: None for a tombstone, and for a put still carrying whatever the schema of the day wrote — a sealed cypher envelope is not opened and a since-dropped field is not projected away.
