Struct PageStats 

pub struct PageStats {
    pub pages_used: usize,
    pub pages_free: usize,
    pub num_pages: usize,
    pub page_size: usize,
    pub seq_len: usize,
    pub layers_materialized: usize,
    pub layers_total: usize,
    pub layers_sliding: usize,
}

A paged cache’s page-table state at a point in time (for monitoring).

Fields

pages_used: usize

Pages holding live KV entries for this sequence.

pages_free: usize

Pages still available in this cache’s arena.

num_pages: usize

Total pages in the arena (pages_used + pages_free when healthy).

page_size: usize

Tokens per page.

seq_len: usize

Cached sequence length in tokens.

layers_materialized: usize

Layers whose arena tensor is actually allocated. Arenas are lazy — a layer materializes on its first write — so this rises through the first prefill and stays below layers_total for models whose sliding layers never touch the paged arena at all.

layers_total: usize

Layers in this cache.

layers_sliding: usize

Layers holding a rolling sliding-window store instead of pages.
