Struct PropHalfLife 

pub struct PropHalfLife {
    pub prop: String,
    pub per_value: Vec<(String, i64)>,
    pub default_ms: i64,
}

Per-node recency half-life keyed by a string prop (e.g. a memory’s kind): a node whose prop value matches a per_value entry decays on that entry’s half-life; absent, non-string, or unmatched values fall to default_ms. None on SearchOptions keeps the flat recency_half_life_ms — the engine stays agnostic about what the prop means; callers supply the map (see topodb-json’s kind constants).

Fields

prop: String

The Str prop to key decay on (e.g. a memory’s kind).

per_value: Vec<(String, i64)>

(prop value, half-life ms) pairs, linear-scanned per candidate — intended for small maps (a handful of kinds, not an open vocabulary).

default_ms: i64

Half-life used when prop is absent, non-Str, or matches no per_value entry.
