# 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`:

```elixir

  def deps do

    [{:lru_cache, "~> 0.1.0"}]

  end

```

  2. Ensure lru_cache is started before your application:

```elixir

  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:

```elixir

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")

```
