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

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

Context Adapter

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

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)
}
