Struct Snapshot 

pub struct Snapshot {
    pub cursor: WatchCursor,
    pub entries: HashMap<String, KvEntry>,
}

Result of loading a snapshot from disk.

Fields

cursor: WatchCursor

Watch cursor at the time of the last checkpoint.

entries: HashMap<String, KvEntry>

Live KV entries keyed by name (deduplicated, deletes applied).

Implementations

impl Snapshot

pub fn stale_keys<'a, I>(&'a self, current_keys: I) -> Vec<&'a str>

where I: IntoIterator<Item = &'a str>,

Keys present in this snapshot but absent from a fresh scan result.

After a cursor-expired fallback to full watch_all(), callers should compare the snapshot against the live key set and emit synthetic Delete events for stale keys to ensure convergence.

Trait Implementations

impl Debug for Snapshot

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

Formats the value using the given formatter.
