Enum WatchEvent 

#[non_exhaustive]
pub enum WatchEvent {
    Put(Entry),
    Delete {
        key: String,
        revision: Revision,
    },
    SnapshotDone,
}

One observation from a keyspace watch.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Put(Entry)

A key’s current value (snapshot replay or live update).

Delete

The key is gone — explicit delete or ephemeral expiry.

Fields

key: String

The key, relative to the keyspace.

revision: Revision

Revision of the deletion itself, strictly greater than every revision the key held before it. Deletes and puts for one key are only ordered through these revisions: a consumer that rewrote the key must ignore a delete whose revision is below its own write’s (the stale echo of an older deletion).

SnapshotDone

The initial snapshot is fully delivered; everything after is live.
