Struct CacheSweep 

pub struct CacheSweep {
    pub schema: &'static str,
    pub budget_bytes: u64,
    pub scanned: u64,
    pub pinned: u64,
    pub evicted: u64,
    pub freed_bytes: u64,
    pub retained_bytes: u64,
    pub over_budget: bool,
    pub generation: i64,
}

What one sweep of the cache tier did.

Reported in full — including what was kept and whether the tier is still over budget — because a sweep that silently declined to free anything and a sweep that had nothing to free look identical from the outside, and they mean opposite things.

Fields

schema: &'static str

Stable schema tag (CACHE_SCHEMA).

budget_bytes: u64

The budget this sweep enforced.

scanned: u64

Entries considered.

pinned: u64

Entries that could not be evicted: written in the current generation with a valid anchor, or the most-recently-used entry, which is always kept.

evicted: u64

Entries deleted.

freed_bytes: u64

Bytes their deletion freed.

retained_bytes: u64

Bytes still held after the sweep.

over_budget: bool

Whether the tier is still over budget after the sweep — which happens when what remains is all pinned. Reported rather than hidden: a bound that silently fails to bind is worse than one that says so.

generation: i64

The generation the tier advanced to. Entries written before it are evictable by the next sweep.
