Struct CacheStats 

pub struct CacheStats { /* private fields */ }

Information regarding the usage of the in-memory cache

Note: hit/miss/eviction metrics are only collected when the “cache_metrics” feature is enabled. used_bytes and budget_bytes are always available.

Implementations

impl CacheStats

pub fn evictions(&self) -> u64

Number of times that data has been evicted, due to the cache being full

To increase the cache size use Builder::set_cache_size

pub fn read_hits(&self) -> u64

Number of times that unmodified data has been read from the cache

pub fn read_misses(&self) -> u64

Number of times that unmodified data was not in the cache and was read from storage

pub fn write_hits(&self) -> u64

Number of times that data modified in a transaction has been read from the cache

pub fn write_misses(&self) -> u64

Number of times that data modified in a transaction was not in the cache and was read from storage

pub fn used_bytes(&self) -> usize

Number of bytes in the cache

pub fn budget_bytes(&self) -> Option<usize>

The configured memory budget, if any.

Returns None when no budget is set (default), meaning the cache sizes are controlled only by Builder::set_cache_size.
