EtcdClient("http://localhost:4001")(system) 14 | 15 | client.setKey("configKey", "configValue") 16 | 17 | val response: Future[EtcdResponse] = client.getKey("configKey") 18 | 19 | response onComplete

``` 28 | 29 | This library is avilable in maven central and is cross compiled for 2.10 and 2.11 30 | 31 | ```XML 32 | 33 | 34 | net.nikore.etcd 35 | scala-etcd_2.11 36 | 0.8 37 | 38 | ``` 39 | 40 | or
