Struct PersistOptions 

pub struct PersistOptions {
    pub filter: PersistFilter,
    pub max_age: Duration,
    pub debounce: Duration,
}

Available on crate feature client only.

Tuning knobs for QueryClient::persist_with.

Default is: every entry, max age 24 hours, 500 ms debounce — a sensible “save the cache to disk shortly after it changes” baseline.

Fields

filter: PersistFilter

Which entries to include.

max_age: Duration

Skip entries older than this at save time.

debounce: Duration

Coalesce bursts of CacheMutation into one save per window.

Passing Duration::ZERO disables the timer-based coalescing window — each bump still races to drain the pending slot, but there is no batching delay (saves still serialize through the drain slot).
