# CasBun

CasBun is a [Bun](https://bun.uptrace.dev/) ORM adapter for [Casbin](https://casbin.org/).

With this library, Casbin can load policy from bun supported database or save policy to it.

##  Installation 

```

go get github.com/mmikalsen/casbun

```

## Simple Example

```go

package main

import (

	"github.com/mmikalsen/casbun"

	"github.com/casbin/casbin/v2"

)

func main() {

	sqldb, _ := sql.Open(sqliteshim.ShimName, "file::memory:?cache=shared"")

	db := bun.NewDB(sqldb, sqlitedialect.New())

	a, _ := casbun.NewAdapter(ctx, db)

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

	// check the permission.

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

	// save the policy back to DB.

	_ = e.SavePolicy()

}

```

## Context Adapter 

`casbun` supports adapter with context, the following is a timeout control implemented using context

```go 

a, _ = casbun.NewAdapter(ctx, db)

// Limited time 300s

ctx, cancel := context.WithTimeout(context.Background(), 300*time.Microsecond)

defer cancel()

err := a.AddPolicyCtx(ctx, "p", "p", []string{"alice", "data1", "read"})

if err != nil {

    panic(err)

}

```
