# LruCache
Simple LRU Cache, implemented with `ets`.
## Installation
The package can be installed as:
1. Add lru_cache to your list of dependencies in `mix.exs`:
def deps do
[{:lru_cache, "~> 0.1.0"}]
end
2. Ensure lru_cache is started before your application:
def application do
[applications: [:lru_cache]]
end
## Using
Typically you want to start the cache from a supervisor:
```elixir
worker(LruCache, [:my_cache, 10])
```
Or starting it manually:
```
LruCache.start_link(:my_cache, 10)
```
The resulting process and ets table will be registered under this alias. Now you can use the cache as follows:
```elixir
LruCache.put(:my_cache, "id", "value")
LruCache.get(:my_cache, "id")
LruCache.get(:my_cache, "id", touch = false)
LruCache.update(:my_cache, "id", "new_value", touch = false)
LruCache.delete(:my_cache, "id")
```
