Module meta 

Algorithm-specific metadata types.

Provides metadata structures for each cache algorithm:

• LfuMeta: Frequency counter for LFU
• LfudaMeta: Frequency for LFUDA (age is cache-global)
• GdsfMeta: Frequency and priority for GDSF Algorithm-Specific Metadata Types (Re-exports)

This module re-exports metadata types from their respective algorithm modules for backward compatibility. For new code, prefer importing directly from the algorithm module (e.g., cache_rs::lfu::LfuMeta).

Metadata Types

Algorithm	Metadata Type	Location
LRU	() (none)	N/A
LFU	LfuMeta	cache_rs::lfu
LFUDA	LfudaMeta	cache_rs::lfuda
SLRU	SlruMeta	cache_rs::slru
GDSF	GdsfMeta	cache_rs::gdsf

Migration Guide

// Old way (still works for backward compatibility)
use cache_rs::meta::LfuMeta;

// New recommended way
use cache_rs::lfu::LfuMeta;

Re-exports

pub use crate::gdsf::GdsfMeta;

pub use crate::lfu::LfuMeta;

pub use crate::lfuda::LfudaMeta;

pub use crate::slru::SlruMeta;
