Struct InMemoryCache 

pub struct InMemoryCache { /* private fields */ }

In-memory cache implementation

Bounded cache backed by moka with per-entry TTL and LRU eviction. Use this as a fallback when Redis is unavailable, or in tests.

Example

use ferro_rs::cache::InMemoryCache;

let cache = InMemoryCache::new();

Implementations

impl InMemoryCache

pub fn new() -> Self

Create a new in-memory cache with default capacity (10,000 entries)

pub fn with_capacity(capacity: u64) -> Self

Create with a custom maximum capacity

pub fn with_prefix(prefix: impl Into<String>) -> Self

Create with a custom prefix
