Struct DefragStats 

#[non_exhaustive]
pub struct DefragStats {
    pub pages_examined: u64,
    pub pages_freed: u64,
    pub values_moved: u64,
    pub freemap_orphans_reclaimed: u64,
}

I36: #[non_exhaustive] for symmetry with DefragOptions and so a future bench-friendly stat (e.g. wall-time elapsed inside the sweep) is not a breaking change.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

pages_examined: u64

pages_freed: u64

values_moved: u64

freemap_orphans_reclaimed: u64

Freemap-typed pages reclaimed by the orphan-sweep — pages a prior crash stranded when it lost the in-memory structural recycle pool (see TransactionManager::reclaim_freemap_orphans). 0 on a clean database. Reported, not gating: a non-zero value means a past crash leaked freemap pages that this pass returned to the bitmap as reusable space.
