Struct PendingCacheState 

pub struct PendingCacheState {
    pub clear_generation: u64,
    pub next_key_generation: u64,
    pub key_generations: HashMap<u64, u64>,
    pub operations: HashMap<u64, PendingCacheOp>,
    pub approx_bytes: usize,
}

State of the pending-operation map. The worker publishes stores only when the queued op’s per-key generation still matches the latest generation seen for that key — a newer invalidate cannot be silently overwritten.

Fields

clear_generation: u64

next_key_generation: u64

key_generations: HashMap<u64, u64>

Per-key, monotonically increasing generation. A Remove resets a key to the same generation as a fresh Store would receive, so any prior Store is observed as stale.

operations: HashMap<u64, PendingCacheOp>

approx_bytes: usize

Per-op byte estimate: sum of entry.bytes for Stores. Used for the max_pending_bytes capacity check; checked/saturating on every transition.
