Struct PlanCache 

pub struct PlanCache { /* private fields */ }

Thread-safe wrapper around LruCache<PlanKey, Arc<CachedPlan>>. Arc lets the actor hand the plan out to a kernel-launch closure that may outlive a subsequent cache eviction.

Implementations

impl PlanCache

pub fn new(cap: usize) -> Self

pub fn put(&self, key: PlanKey, plan: Arc<CachedPlan>)

pub fn len(&self) -> usize

Cache size for tests / observability.
