Struct ProofCacheStats

Source

pub struct ProofCacheStats {
    pub hits: u64,
    pub misses: u64,
    pub evictions: u64,
    pub invalidations: u64,
}

Expand description

Cumulative statistics for a ProofCachingLayer.

Fields§

§hits: u64

Total successful lookups (stale entries do not count as hits).

§misses: u64

Total failed lookups (no entry or stale entry).

§evictions: u64

Total entries removed by LFU eviction to make room for new entries.

§invalidations: u64

Total entries removed by explicit KB-version invalidation.

Implementations§

Source §

impl ProofCacheStats

Source

pub fn hit_rate(&self) -> f64

Fraction of lookups that resulted in a cache hit, in [0.0, 1.0].

Returns 0.0 when no lookups have been performed.
