Struct Watermark 

pub struct Watermark { /* private fields */ }

Tracks how far a sweep may claim to have got.

The rule is one sentence: never past a transcript that failed. A failure pins the watermark to just before it, so the next sweep tries that transcript again — and the archive check keeps the ones that succeeded after it from being imported twice.

Implementations

impl Watermark

pub fn new() -> Self

pub fn handled(&mut self, transcript: &TranscriptRef)

A transcript was dealt with — archived, empty, or a known duplicate.

pub fn failed(&mut self)

A transcript failed; the watermark stops here.

pub fn reached(&self) -> Option<SystemTime>

How far the sweep got, if anywhere.

pub fn commit(&self, memory_dir: &Path, source: Source)

Persist the mark, when there is one.
