Struct PersistentCacheValue 

pub struct PersistentCacheValue {
    pub fastest_index: usize,
    pub results: Vec<AutotuneResult>,
    pub bounds: Option<Bounds>,
    pub limit: Option<Duration>,
}

Persistent cache entry

Only fastest_index is read back: hydration seeds the in-memory cache from it and nothing else. Everything below it is stored so a cache entry can be inspected after the fact — why a kernel won, against which measurements, and under which bounds — which is the question that cannot be answered from a live process once tuning is over. That is also why the type is pub: reading an entry back is the point.

Fields

fastest_index: usize

Index of the fastest candidate operation.

results: Vec<AutotuneResult>

Benchmarking results for all autotune candidates.

bounds: Option<Bounds>

Optional input size bounds for which the autotune result applies.

Defaulted, so entries written before this field existed still decode. Without it every cached key on every existing installation would fail to read and re-tune from scratch.

limit: Option<Duration>

Optional execution time limit for the autotune process.

Defaulted for the same reason as bounds.
