Struct GdsfCacheConfig

pub struct GdsfCacheConfig { /* private fields */ }

Configuration for a GDSF (Greedy Dual-Size Frequency) cache.

GDSF assigns a priority to each item based on the formula: Priority = (Frequency / Size) + Global_Age

Examples

use cache_rs::config::gdsf::GdsfCacheConfig;
use core::num::NonZeroUsize;

// Create a config with capacity of 100 items and initial age of 0.0
let config = GdsfCacheConfig::new(NonZeroUsize::new(100).unwrap());

assert_eq!(config.capacity(), NonZeroUsize::new(100).unwrap());
assert_eq!(config.initial_age(), 0.0);

Implementations

impl GdsfCacheConfig

pub fn new(capacity: NonZeroUsize) -> Self

Creates a new configuration for a GDSF cache with initial age of 0.0.

Arguments

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

pub fn with_initial_age(capacity: NonZeroUsize, initial_age: f64) -> Self

Creates a new configuration for a GDSF 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) -> f64

Returns the initial global age value.
