ETCD adapter is the policy storage adapter for [Casbin](https://github.com/casbin/casbin). With this library, Casbin can load policy from ETCD and save policy to it. ETCD adapter support the __Auto-Save__ feature for Casbin policy. This means it can support adding a single policy rule to the storage, or removing a single policy rule from the storage.

## Installation

```bash

go get github.com/sebastianliu/etcd-adapter

```

## Sample Example

```go

package main

import (

	"github.com/sebastianliu/etcd-adapter"

	"github.com/casbin/casbin"

)

func main() {

	// Initialize a casbin etcd adapter and use it in a Casbin enforcer:

	// The adapter will use the ETCD and a named path with the key you give.

	// If not provided, the adapter will try to use the default value casbin_policy.

	// If you have namespace to distinguish keys in your etcd, you can use your_namespace/casbin_root_path

	a := etcdadapter.NewAdapter([]string{"http://127.0.0.1:2379"}, "casbin_policy_test") // Your etcd endpoints and the path key.

	e := casbin.NewEnforcer("rbac_model.conf", a)

	// Load the policy from ETCD.

	e.LoadPolicy()

	// Check the permission.

	e.Enforce("alice", "data1", "read")

	// Modify the policy.

	// e.AddPolicy(...)

	// e.RemovePolicy(...)

	// Save the policy back to DB.

	e.SavePolicy()

}
