Struct ResolvedTinyLfu 

pub struct ResolvedTinyLfu {
    pub sketch_bytes: usize,
    pub promotion_threshold: u32,
    pub probation_target_pct: u64,
    pub aging_halflife_sec: u64,
}

Resolved W-TinyLFU tuning knobs. See ResolvedCache::tinylfu.

Fields

sketch_bytes: usize

Count-min sketch size in bytes. Default crate::config::DEFAULT_TINYLFU_SKETCH_BYTES.

promotion_threshold: u32

Prior sightings before a probation member promotes to main. Default crate::config::DEFAULT_TINYLFU_PROMOTION_THRESHOLD.

probation_target_pct: u64

Percent of cache.cache_size_mb the probation segment is capped to. Validated to [1, 50]. Default crate::config::DEFAULT_TINYLFU_PROBATION_TARGET_PCT.

aging_halflife_sec: u64

Reserved: half-life in seconds for aging the frequency sketch. Resolved and stored but not currently consulted by the shipped sketch (fixed sample-count reset, not wall-clock aging). Default crate::config::DEFAULT_TINYLFU_AGING_HALFLIFE_SEC.
