Is there any examples of how to write code that callable only by Enigma contract on Ethereum blockchain in Solidity? I found this before

```
modifier onlyEnigma() {
require(msg.sender == address(enigma));
_;
  }

```

But this is a 2018 version of Enigma protocol.  
I have 2 questions:

1. How to write a Solidity function callable only by enigma?
2. How to write a Rust callback function that calls arbitrary functions of smart contract deployed on Ethereum.

I just need some classic examples
