Implementations

impl Cache

pub fn new(store: Arc<dyn KvStore>) -> Self

pub async fn get_json<T: DeserializeOwned>(&self, key: &str) -> Option<T>

pub async fn set_json<T: Serialize>( &self, key: &str, val: &T, ttl: Option<Duration>, ) -> Result<(), CacheError>

pub async fn remember<T, F, Fut>( &self, key: &str, ttl: Option<Duration>, f: F, ) -> Result<T, CacheError>

where T: Serialize + DeserializeOwned, F: FnOnce() -> Fut, Fut: Future<Output = Result<T, CacheError>>,

Return cached value or compute, store, and return.

pub async fn invalidate(&self, key: &str)
