Struct MokaCache 

pub struct MokaCache { /* private fields */ }

Moka in-memory cache with per-key TTL support

This is the default L1 (hot tier) cache backend, providing:

• Fast in-memory access (< 1ms latency)
• Automatic eviction via LRU
• Per-key TTL support
• Statistics tracking

Implementations

impl MokaCache

pub fn new(config: MokaCacheConfig) -> Result<Self>

Create new Moka cache

Errors

Returns an error if the cache cannot be initialized.

Trait Implementations

impl CacheBackend for MokaCache

Implement CacheBackend trait for MokaCache

This allows MokaCache to be used as a pluggable backend in the multi-tier cache system.

fn get<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Option<Value>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Get value from cache by key

fn set_with_ttl<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, value: Value, ttl: Duration, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Set value in cache with time-to-live

fn remove<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Remove value from cache

fn health_check<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = bool> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Check if cache backend is healthy

fn name(&self) -> &'static str

Get the name of this cache backend
