RefcountEntry

Struct RefcountEntry 

Source
pub struct RefcountEntry {
    pub refcount: u32,
    pub first_seen_unix_ms: u64,
    pub last_seen_unix_ms: u64,
    pub pinned: bool,
    pub size_bytes: Option<u64>,
}
Expand description

Per-hash refcount entry stored in the BlobRefcountTable.

Fields§

§refcount: u32

Current outstanding references from any source (chain folds, CortEX, queries, scanner). Saturating arithmetic on both incr and decr so a buggy source can’t underflow or wrap.

§first_seen_unix_ms: u64

Wall-clock unix milliseconds when this hash was first observed (first incr OR first store_observed). Used by super::refcount::should_sweep against the retention floor.

§last_seen_unix_ms: u64

Wall-clock unix milliseconds of the most recent touch (incr / fetch / sweep-skipped). Drives the BlobStat::last_seen_unix_ms field surfaced via the adapter stat path.

§pinned: bool

true while the operator has pinned the hash via BlobRefcountTable::pin. Pinned hashes survive GC regardless of refcount / retention floor.

§size_bytes: Option<u64>

Payload size in bytes for this hash. Some(n) whenever the local adapter has observed a store; None for hashes that only entered the table via incr from a remote source (the chunk isn’t local yet — the size is the peer’s to advertise).
