Struct DedupStats 

pub struct DedupStats {
    pub total_requests: u64,
    pub cache_hits: u64,
    pub cache_misses: u64,
    pub evictions: u64,
}

Aggregate statistics for the deduplication cache.

All counters are monotonically increasing; they are never reset unless DedupCache::clear is called.

Fields

total_requests: u64

Total number of DedupCache::get calls (hits + misses).

cache_hits: u64

Number of lookups that returned a cached response.

cache_misses: u64

Number of lookups that found no valid entry.

evictions: u64

Number of entries evicted due to capacity overflow or TTL expiry.

Fraction of lookups that were cache hits, in [0.0, 1.0].

Returns 0.0 if no requests have been made yet.

pub fn summary(&self) -> String

Human-readable one-line summary of the statistics.
