Struct ResizableStats 

pub struct ResizableStats {
    pub hits: u64,
    pub misses: u64,
    pub evictions: u64,
}

Point-in-time stats sample from a registered cache.

All counters are monotonic-since-construction. The policy compares the delta between consecutive snapshots, so the absolute values only need to be consistent within a single sample.

Fields

hits: u64

Successful lookups served from the cache.

misses: u64

Lookups that missed and required falling back to the inner store.

evictions: u64

Total evictions over the cache’s lifetime.

Implementations

impl ResizableStats

pub fn hit_rate(&self) -> Option<f64>

Fraction of hits + misses served from the cache. None when no lookups have occurred (avoids division by zero and a misleading 0.0 reading on idle caches).
