Struct LogAnchor 

pub struct LogAnchor {
    pub database: u64,
    pub durable: u64,
    pub lanes: Vec<LaneStart>,
    pub voids: Vec<u64>,
}

How much of the log a file holds.

Fields

database: u64

The id every segment header of this database’s log carries.

durable: u64

The durable cut: every commit at or below it is in the file.

lanes: Vec<LaneStart>

Where replay starts, one entry per lane.

voids: Vec<u64>

Timestamps above the cut that were lost and must never be replayed, in order.

Implementations

impl LogAnchor

pub fn replays(&self, ts: u64) -> bool

Whether a commit at ts is one replay applies: above the cut and not void.
