Fields

cache_hits: u64

cache_miss: u64

cache_shortfall: u64

reloads: u64

reload_ms_total: u128

total_cap: usize

total_cost: usize

eviction_count: u64

Total evictions since client creation

approx_bytes: usize

Approximate bytes used by cache (rough estimate)

byte_cap: usize

Effective byte cap for cached hits (0 = disabled by explicit operator override)

eviction_policy: &'static str

Active eviction/admission policy for prefix result cache

ghost_entries: usize

Number of S3-FIFO ghost entries retained for adaptive admission

admission_rejects: u64

Number of cache insertions rejected by adaptive admission

prewarm_scheduled: u64

Number of adaptive query prewarm jobs scheduled from hot prefix-cache state.

prewarm_skipped_pressure: u64

Number of adaptive query prewarm jobs skipped because cache pressure was high.

reader_generation: Option<u64>

Last observed Tantivy reader generation signature for cursor continuity metadata.

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() -> Self

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.
