## Installing

You can install `Memcache` by adding it as a dependecy to your
project's `mix.exs` file:

end
```

## Examples

case response.status do
  :ok ->
    {:ok, response.value}
  status ->
    {:error, status}
end
```

### Fetch

```elixir
value = Memcache.fetch!("hello", fn ->
  "world"
end)

# value == "world"

value = Memcache.fetch!("hello", fn ->
  "world2"
end)

# value == "world"
```
