1//! Shared decay-window type for engines that age observations by tick count.
2//!
3//! `DecayWindow` configures how many ticks an observation or route entry
4//! remains fresh and how soon the next engine refresh should run. Proactive
5//! next-hop engines (BATMAN variants, Babel, OLSRv2) use this primitive to
6//! prune stale per-neighbor evidence and keep refresh cadence legible.
7// proc-macro-scope: host support primitive intentionally stays outside #[public_model].

11/// Per-engine staleness and refresh window configuration.
12///
13/// `stale_after_ticks` is the number of ticks an observation may age before it
14/// is dropped. `next_refresh_within_ticks` is the upper bound on how soon the
15/// next engine tick should refresh derived tables.
