Struct CacheStats 

pub struct CacheStats {
    pub entries: usize,
    pub bytes: u64,
    pub hits: u64,
    pub misses: u64,
    pub hit_rate: f64,
    pub evictions: u64,
}

Summary statistics for a namespace (or the whole cache).

Fields

entries: usize

Live (non-deleted, non-expired) entries.

bytes: u64

Live payload bytes.

hits: u64

Hits recorded on this handle since open.

misses: u64

Misses recorded on this handle since open (includes TTL-expired and non-existent keys — both look the same to the caller).

hit_rate: f64

Hits divided by (hits + misses); 0.0 if no lookups.

evictions: u64

Directory entries evicted (by LRU-under-budget) since open.
