In rust we can declare a function with `#[init]` annotation - this function will be called right after canister’s code installation - so it works like a constructor.

How can I pass arguments to this function?

If you deploy with `dfx`, run

```auto
dfx deploy --no-wallet --argument '(…your args here…)'

```
