Description

I am loading the abi.json directly in line (as shown here) but getting a use of undeclared type IERC20` error when compiling.

I tried this code:

    abigen!(IERC20, "./data/IERC20.json");
    const RPC_URL: &str = "https://eth.llamarpc.com";
    const WETH_ADDRESS: &str = "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2";

    let provider = Provider::<Http>::try_from(RPC_URL)?;
    let client = Arc::new(provider);
    let address: Address = WETH_ADDRESS.parse()?;
    let contract = IERC20::new(address, client);

I expected to see this happen: being able to load the abi from json and use it to create a new contract instance.

Instead, this happened:use of undeclared type IERC20` error when compiling.

Found out that there is an error depending on how is the folder named: I had my abis in /data/ folder and that is failing but works fine if reading from ./abis/. Weird error though
