In Aptos how do you you call initialize a constructor when deploying the contract with Aptos CLI

Question

I want to know what is the constructor function (that is called during deployment) in Aptos move contract and how initialize a string value on the contract level when calling it. How to achieve this and how do I call it with argument with the aptos move publish command?

Answer 1

You might be looking for init_module. This function runs automatically just when you publish your module.

An example:

fun init_module(sender: &signer) {
    aptos_framework::managed_coin::initialize<MoonCoin>(
        sender,
        b"Moon Coin",
        b"MOON",
        6,
        false,
    );
}

From aptos-move/move-examples/moon_coin/sources/MoonCoin.move in aptos-core.
