Hi - which code specifically did you copy? eg: which step were you on when you encountered this error?

This code:

use super::schema;
use shopify_function::prelude::*;
use shopify_function::Result;

#[shopify_function]
fn run(input: schema::run::Input) -> Result<schema::FunctionRunResult> {
    let no_changes = schema::FunctionRunResult { operations: vec![] };

    // Get the cart total from the function input, and return early if it's below 100
    let cart_total: f64 = input.cart().cost().total_amount().amount().as_f64();
    if cart_total < 100.0 {
        eprintln!("Cart total is not high enough, no need to hide the payment method.");
        return Ok(no_changes);
    }

    // Find the payment method to hide, and create a hide output operation from it
    let operations = input
        .payment_methods()
        .iter()
        .find(|&method| method.name() == "Cash on Delivery")
        .map(|method| {
            vec![schema::Operation::Hide(schema::HideOperation {
                payment_method_id: method.id().to_string(),
                placements: None,
            })]
        })
        .unwrap_or_default();

    Ok(schema::FunctionRunResult { operations })
}

Which version of the Shopify CLI are you using? If you’re not on the most recent, can you update and try again?
