kevy-window

The sliding-window runtime for scalar and text indexes.

Shared by the kevy server and the embedded store, so the two faces cannot drift: boundary maintenance, the eviction slide, and the cold half of range / count are one implementation, not two.

Why a slide can fail safely

Cold segments are derived spill, not truth — the rows stay hot and the index is rebuilt from them on boot. So a failed slide simply leaves the tree untouched: the batch is read before it is cut, and a restart drops the segment set and re-slides from the rows.

That property is the reason this crate can be aggressive about eviction without needing a crash-recovery protocol of its own.

Every public item is documented, and the lint holds it that way.

Pure Rust, zero dependencies. Part of kevy.
