Struct async_cache::AsyncCache

pub struct AsyncCache<T, F>where
    T: Send + Sync + Clone + 'static,
    F: Fetcher<T> + Sync + Send + Clone + 'static,{ /* private fields */ }

Implementations

impl<T, F> AsyncCache<T, F>where T: Send + Sync + Clone + 'static, F: Fetcher<T> + Sync + Send + Clone + 'static,

pub fn set_default(&self, key: FastStr, value: T)

SetDefault sets the default value of given key if it is new to the cache. It is useful for cache warming up.

pub async fn get(&self, key: FastStr) -> Option<T>

Returns None if first fetch result is err

pub fn get_or_set(&self, key: FastStr, value: T) -> T

pub async fn delete(&self, should_delete: impl Fn(&str) -> bool)

Trait Implementations

impl<T, F> Clone for AsyncCache<T, F>where T: Send + Sync + Clone + 'static + Clone, F: Fetcher<T> + Sync + Send + Clone + 'static + Clone,

fn clone(&self) -> AsyncCache<T, F>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
