Struct MemoryCache 

pub struct MemoryCache { /* private fields */ }

In-memory LRU cache store.

Enforces a maximum byte limit. When the limit is exceeded, the least recently accessed entries are evicted. Thread-safe via Mutex.

Implementations

impl MemoryCache

pub fn new(max_bytes: usize) -> Self

Create a new memory cache with a maximum byte limit.

pub fn len(&self) -> usize

Number of entries currently in the cache.

pub fn is_empty(&self) -> bool

Whether the cache is empty.

pub fn current_bytes(&self) -> usize

Current memory usage in bytes.

pub fn clear(&self)

Clear all entries.
