//! Example of deploying a contract from an artifact using the `sol!` macro to Anvil and interacting

//! with it.

use alloy::{primitives::U256, providers::ProviderBuilder, sol};

use eyre::Result;

// Codegen from artifact.

sol!(

#[allow(missing_docs)]

#[sol(rpc)]

Counter,

"examples/artifacts/Counter.json"

);

#[tokio::main]

async fn main() -> Result<()> {

// Spin up a local Anvil node.

// Ensure `anvil` is available in $PATH.

let provider = ProviderBuilder::new().on_anvil_with_wallet();

// Deploy the `Counter` contract.

let contract = Counter::deploy(&provider).await?;

println!("Deployed contract at address: {}", contract.address());

// Set the number to 42.

let builder = contract.setNumber(U256::from(42));

let tx_hash = builder.send().await?.watch().await?;

println!("Set number to 42: {tx_hash}");

// Increment the number to 43.

let builder = contract.increment();

let tx_hash = builder.send().await?.watch().await?;

println!("Incremented number: {tx_hash}");

// Retrieve the number, which should be 43.

let builder = contract.number();

// Note: because the artifact generated by `solc` does not include named return values it is

// not possible to derive the return value name `number` from the artifact. This means that the

// return value must be accessed by index - as if it is an unnamed value.

// If you prefer to use named return values, it is recommended to embed the Solidity code

// directly in the `sol!` macro as shown in `deploy_from_contract.rs`.

let number = builder.call().await?._0;

println!("Retrieved number: {number}");

Ok(())
