Struct PersistSnapshot 

pub struct PersistSnapshot {
    pub entries: HashMap<String, PersistedEntry>,
    pub version: u32,
}

Available on crate feature client only.

A full snapshot of the persistable cache, ready to hand to a Persister.

Fields

entries: HashMap<String, PersistedEntry>

The persistable entries, keyed by QueryKey path string.

Keys are stored as their to_path() String form so the snapshot is self-contained (no Arc aliasing across processes) and serializable.

version: u32

Format version; see PERSIST_VERSION and PersistError::VersionMismatch.
