Struct HotCache 

pub struct HotCache { /* private fields */ }

In-memory hot cache for semantic query dedup.

Thin wrapper around totalreclaw_core::hotcache::HotCache<Vec<MemoryEntry>>.

Implementations

impl HotCache

pub fn new() -> Self

Create an empty hot cache with default settings (30 entries, cosine >= 0.85).

pub fn lookup(&self, query_embedding: &[f32]) -> Option<Vec<MemoryEntry>>

Check if a semantically similar query has already been answered.

Returns cached results if a query with cosine >= 0.85 exists.

pub fn insert(&mut self, query_embedding: Vec<f32>, results: Vec<MemoryEntry>)

Insert a query result into the cache.

Evicts the oldest entry if the cache is full.

pub fn clear(&mut self)

Clear the cache (e.g., after a store operation).

pub fn len(&self) -> usize

Number of cached entries.

pub fn is_empty(&self) -> bool

Whether the cache is empty.

Trait Implementations

impl Default for HotCache

fn default() -> Self

Returns the “default value” for a type.
