Struct MemoryCache 

pub struct MemoryCache { /* private fields */ }

Memory cache implementation using moka::sync::Cache

Features:

• Lock-free concurrent access
• TinyLFU eviction policy (better hit rate than LRU)
• Per-entry TTL support via Expiry trait
• Automatic expiration cleanup

Implementations

impl MemoryCache

pub fn new(max_size: usize) -> Self

Create a new memory cache

Arguments

• max_size - Maximum number of cache entries

Trait Implementations

impl Cache for MemoryCache

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

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

获取缓存值

fn set<'life0, 'async_trait>( &'life0 self, key: String, value: String, ttl: Option<Duration>, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

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

设置缓存值

fn delete<'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,

删除缓存值

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

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

清除所有缓存条目

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

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