Expand description

Cache trait. Implementations: in-memory (default), on-disk (MVP 5).

§Examples

use mos_cache::{Cache, CacheKey, InMemoryCache};
use mos_core::ContentHash;

let mut cache = InMemoryCache::default();
let key = CacheKey(ContentHash(7));
cache.put(key, vec![1, 2, 3]);

assert_eq!(cache.get(&key), Some(vec![1, 2, 3]));

Required Methods§

Source

fn get(&self, key: &CacheKey) -> Option<Vec<u8>>

Return a cached payload for key, if present.

§Examples
use mos_cache::{Cache, CacheKey, InMemoryCache};
use mos_core::ContentHash;

let cache = InMemoryCache::default();

assert_eq!(cache.get(&CacheKey(ContentHash(1))), None);
Source

fn put(&mut self, key: CacheKey, value: Vec<u8>)

Store value under key, replacing any previous value.

§Examples
use mos_cache::{Cache, CacheKey, InMemoryCache};
use mos_core::ContentHash;

let mut cache = InMemoryCache::default();
let key = CacheKey(ContentHash(1));
cache.put(key, vec![9]);

assert_eq!(cache.get(&key), Some(vec![9]));
