Struct MemoStats 

pub struct MemoStats {
    pub hits: u64,
    pub misses: u64,
    pub evictions: u64,
    pub expired_on_access: u64,
    pub current_entries: usize,
}

Runtime statistics for a MemoCache.

Distinct from CacheStats in cache.rs — these counters use u64 (rather than usize) and track an extra dimension: entries that were found but had already expired.

Fields

hits: u64

Number of lookups that returned a cached value.

misses: u64

Number of lookups that found no entry at all.

evictions: u64

Number of entries that were evicted to make room for new ones.

expired_on_access: u64

Number of lookups that found an entry but it had expired (TTL).

current_entries: usize

Number of entries currently stored in the cache.

Implementations

impl MemoStats

pub fn hit_rate(&self) -> f64

Fraction of total lookups (hit + miss + expired) that were hits.

Returns 0.0 when no lookups have been made.

pub fn total_lookups(&self) -> u64

Total number of cache lookups (hits + misses + expired accesses).

pub fn summary(&self) -> String

Human-readable one-line summary.

Performs copy-assignment from source.

impl Debug for MemoStats

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Default for MemoStats

fn default() -> MemoStats
