Struct HysteresisConfig 

pub struct HysteresisConfig {
    pub margin: f32,
    pub min_dwell: u64,
}

Anti-thrash policy for slot swaps (mirrors the llama.cpp hot-expert cache hysteresis gate + dwell). Both knobs default to off so existing callers keep the plain top-S paired-swap behavior.

Fields

margin: f32

A challenger expert must exceed an incumbent’s hit count by this fraction before it may evict it (e.g. 0.25 = “must be ≥25% hotter”). 0.0 disables the margin so any strictly-hotter expert wins.

min_dwell: u64

An incumbent may not be evicted until it has been resident for at least this many refreshes (dwell / minimum-hold). 0 disables the dwell gate.

Implementations

impl HysteresisConfig

pub fn is_active(&self) -> bool
