Struct LfudaCacheConfig

pub struct LfudaCacheConfig { /* private fields */ }

Configuration for an LFUDA (Least Frequently Used with Dynamic Aging) cache.

LFUDA enhances LFU by using a dynamic aging mechanism that prevents old frequently-accessed items from permanently blocking new items.

Examples

use cache_rs::config::lfuda::LfudaCacheConfig;
use core::num::NonZeroUsize;

// Create a config with capacity of 100 items and initial age of 0
let config = LfudaCacheConfig::new(NonZeroUsize::new(100).unwrap());

assert_eq!(config.capacity(), NonZeroUsize::new(100).unwrap());
assert_eq!(config.initial_age(), 0);

Implementations

impl LfudaCacheConfig

pub fn new(capacity: NonZeroUsize) -> Self

Creates a new configuration for an LFUDA cache with initial age of 0.

Arguments

• capacity - Maximum number of key-value pairs the cache can hold

pub fn with_initial_age(capacity: NonZeroUsize, initial_age: usize) -> Self

Creates a new configuration for an LFUDA cache with a specific initial age.

Arguments

• capacity - Maximum number of key-value pairs the cache can hold
• initial_age - Initial global age value

pub fn capacity(&self) -> NonZeroUsize

Returns the maximum number of key-value pairs the cache can hold.

pub fn initial_age(&self) -> usize

Returns the initial global age value.
