Struct InMemoryCache 

pub struct InMemoryCache { /* private fields */ }

In-memory cache for Discord entities with Time-To-Live (TTL).

Uses DashMap for lock-free concurrent access. All stored values are wrapped in Arc for efficient sharing.

TTL Behavior

• Default TTL is 1 hour
• Expired items are filtered out on read
• Call InMemoryCache::sweep to remove expired items and free memory

Implementations

impl InMemoryCache

pub fn new() -> Self

Create a new empty cache with default TTL (1 hour).

pub fn with_ttl(ttl: Duration) -> Self

Create a new cache with a custom TTL.

pub fn sweep(&self) -> usize

Garbage collect expired items.

Returns the number of items removed.
