Struct TypedCache 

pub struct TypedCache<V: Send + Sync + 'static> { /* private fields */ }

A type-erased, cloneable cache for values of type V.

Wraps any CacheBackend<V> behind an Arc<dyn …>, so it can be cloned cheaply and stored in structs without generics leaking into the public API.

The concrete backend is selected via CacheConfig::backend.

Example

use pubmed_client::cache::{TypedCache, MemoryCache, CacheConfig};

let config = CacheConfig::default();
let cache: TypedCache<String> = TypedCache::new(MemoryCache::new(&config));
cache.insert("key".to_string(), "value".to_string()).await;
assert_eq!(cache.get("key").await, Some("value".to_string()));

Implementations

impl<V: Send + Sync + 'static> TypedCache<V>

pub fn new(backend: impl CacheBackend<V> + 'static) -> Self

Wrap backend in a TypedCache.

pub async fn get(&self, key: &str) -> Option<V>

pub async fn insert(&self, key: String, value: V)

pub async fn clear(&self)

pub fn entry_count(&self) -> u64

pub async fn sync(&self)

Trait Implementations

impl<V: Clone + Send + Sync + 'static> Clone for TypedCache<V>

fn clone(&self) -> TypedCache<V>

Returns a duplicate of the value.

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

Performs copy-assignment from source.
