Struct CacheStats 

pub struct CacheStats {
    pub entries: usize,
    pub retained_bytes: usize,
    pub hits: u64,
    pub misses: u64,
    pub evictions: u64,
    pub clears: u64,
}

Entry, retained-byte, and event accounting for one cache.

retained_bytes reports the cache-owned logical payload estimate. It does not include allocator arena slack, operating-system RSS, or memory retained by unrelated process allocators.

Examples

use tenferro_tensor::CacheStats;

let stats = CacheStats {
    entries: 2,
    retained_bytes: 128,
    hits: 3,
    misses: 4,
    evictions: 0,
    clears: 0,
};
assert_eq!(stats.entries, 2);
assert_eq!(stats.retained_bytes, 128);
assert_eq!(stats.hits, 3);

Fields

entries: usize

Number of cache entries currently retained.

retained_bytes: usize

Cache-owned retained payload estimate in bytes.

hits: u64

Successful cache lookups.

misses: u64

Failed cache lookups or typed lookup mismatches.

evictions: u64

Entries evicted by cache retention limits.

clears: u64

Explicit cache clear operations.

Implementations

impl CacheStats

pub fn empty() -> CacheStats

Return an empty stats snapshot.

Examples

use tenferro_tensor::CacheStats;

let stats = CacheStats::empty();
assert_eq!(stats.entries, 0);
assert_eq!(stats.retained_bytes, 0);

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<(), Error>

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.

impl Copy for CacheStats
