Struct ColdStore 

pub struct ColdStore { /* private fields */ }

Unbounded long-term memory archive. Entries are never deleted.

recall returns top-N entries by a blended score of reward × recency.

Examples

use lmm_agent::cognition::memory::{ColdStore, MemoryEntry};

let mut cold = ColdStore::default();
cold.promote(MemoryEntry::new("fact about Rust".into(), 0.9, 0));
assert_eq!(cold.len(), 1);
let recalled = cold.recall("Rust", 1);
assert_eq!(recalled[0].content, "fact about Rust");

Implementations

impl ColdStore

pub fn promote(&mut self, entry: MemoryEntry)

Appends an entry to the archive.

pub fn len(&self) -> usize

Returns the total number of entries in the archive.

pub fn is_empty(&self) -> bool

Returns true when no entries have been archived.

pub fn all(&self) -> &[MemoryEntry]

Returns all archived entries (insertion order).

pub fn recall(&self, query: &str, top_n: usize) -> Vec<&MemoryEntry>

Returns the top-n entries most relevant to query, blending token-overlap with a recency factor.

Examples

use lmm_agent::cognition::memory::{ColdStore, MemoryEntry};

let mut cold = ColdStore::default();
cold.promote(MemoryEntry::new("old fact".into(), 0.5, 0));
cold.promote(MemoryEntry::new("Rust ownership facts recent".into(), 0.8, 5));
let top = cold.recall("Rust", 1);
assert_eq!(top[0].content, "Rust ownership facts recent");

pub fn snapshot(&self) -> Vec<String>

Returns a snapshot of all content strings (newest-first).
