Struct PluginMemoryCache 

pub struct PluginMemoryCache { /* private fields */ }

插件内存缓存实例

每个插件拥有一个独立的 PluginMemoryCache 实例，所有操作自动添加命名空间前缀

Trait Implementations

impl Cache for PluginMemoryCache

fn get<'life0, 'life1, 'async_trait, T>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Option<T>, CacheError>> + Send + 'async_trait>>

where T: DeserializeOwned + 'async_trait, Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

获取缓存值

fn set<'life0, 'life1, 'life2, 'async_trait, T>( &'life0 self, key: &'life1 str, value: &'life2 T, _ttl: Option<Duration>, ) -> Pin<Box<dyn Future<Output = Result<(), CacheError>> + Send + 'async_trait>>

where T: Serialize + Sync + 'async_trait, Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

设置缓存值

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

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

删除缓存值

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

获取剩余过期时间

fn clear<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<u64, CacheError>> + Send + 'async_trait>>

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

清空所有缓存
