Struct CacheStats 

pub struct CacheStats {
    pub hits: u64,
    pub misses: u64,
    pub inserts: u64,
    pub capacity_evictions: u64,
    pub invalidations: u64,
    pub single_flight_joins: u64,
    pub single_flight_errors: u64,
}

Counters reported by ClockTtlCache::stats. Monotonic since construction (or the most recent reset_stats call); returned by value so callers own a snapshot, not a reference into the live atomics.

Fields

hits: u64

Successful get hits. TTL-expired entries evicted on access count as misses, not hits.

misses: u64

get calls that returned None (key absent or expired). Includes single-flight cache lookups inside get_or_try_insert_with.

inserts: u64

Successful inserts (fresh and overwriting).

capacity_evictions: u64

Entries evicted by LRU capacity pressure during inserts.

invalidations: u64

Entries removed by explicit invalidate / invalidate_by / invalidate_all / cleanup_expired calls.

single_flight_joins: u64

Concurrent get_or_try_insert_with calls that joined an in-flight load instead of starting their own. High values mean duplicate fetches successfully avoided.

single_flight_errors: u64

get_or_try_insert_with fetcher invocations that returned an error. The cell is removed on error so subsequent callers retry rather than re-await a known-failing future.

Trait Implementations

impl Clone for CacheStats

fn clone(&self) -> CacheStats

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CacheStats

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

Formats the value using the given formatter.

impl Default for CacheStats

fn default() -> CacheStats

Returns the “default value” for a type.

impl PartialEq for CacheStats

fn eq(&self, other: &CacheStats) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
