Statistics related to the Arc

Fields

reader_ops: u64

The number of attempts to read from the cache

reader_hits: u64

The number of hits during all read operations on the primary cache.

reader_tlocal_hits: u64

The number of hits during all read operations on the thread local caches. If thread local storage is disabled, this will always be 0. This is measured in seperately to a reader hit - either we hit the main cache, or the tlocal, never both.

reader_tlocal_includes: u64

The number of inclusions to the thread local storage. If thread local storage is disabled, this will always be 0. This is measured in addition to reader async inclusions.

reader_includes: u64

The number of successful async main cache inclusions through read operations.

reader_failed_includes: u64

The number of failed async main cache inclusions through read operations.

write_read_ops: u64

The number of attempts to read from the write cache

write_hits: u64

The number of cache hits during all write operations.

write_includes: u64

The number of inclusions through write operations. This does NOT track updates to the main cache, where the updates may change the value.

write_modifies: u64

The number of modifications to the cache content during a write. This does NOT track inclusions, where includes add a new value.

shared_max: u64

The maximum number of items in the shared cache.

freq: u64

The number of items in the frequent set at this point in time.

recent: u64

The number of items in the recent set at this point in time.

freq_evicts: u64

The number of items evicted from the frequent over all time.

recent_evicts: u64

The number of items evicted from the recent set over all time.

p_weight: u64

The current cache weight between recent and frequent.

all_seen_keys: u64

The number of total keys seen through the cache’s lifetime.

Implementations

impl CacheStats

pub fn change_since(&self, previous: &CacheStats) -> CacheStatsDiff

Calculate the change since a previous point in time of the stats of this cache.

Trait Implementations

impl Clone for CacheStats

fn clone(&self) -> CacheStats

Returns a copy 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<CacheStats> for CacheStats

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

This method tests for self and other values to be equal, and is used by ==.
