In motoko, there is a “Actor classes”, does Rust have a similar approach？

```auto
Actor classes enable you to create networks of actors programmatically. Currently, actor classes have to be defined in a separate source file. 

```

Make update calls `create_canister` and `install_code` to `management` canister

```nohighlight
use ic_cdk::export::candid::{encode_args, Principal};
use ic_cdk::api::call::{call, call_with_payment, CallResult};

let management_canister = Principal::management_canister();

# Next is untested code
let req = ...
let cycles = ...
call_with_payment(management_canister, "create_canister", (req,), cycles).await # will return -> CallResult<()>
call(management_canister, "install_code", (req2,)).await

# Use encode_args for arguments encoding

```
