coins_iteration.rs

#[test]
fn can_loop_through_coins() -> StdResult<()> {
    let mut coins = Coins::default();
    coins.add(Coin::new(123, "uwasm"))?;
    coins.add(Coin::new(7, "uwasm"))?;
    coins.add(Coin::new(65, "uatom"))?;

    for borrowed_coin in coins.iter() {
        println!("Element: {borrowed_coin}");
    }

    for owned_coin in coins {

    Ok(())
}

// Prints
// Element: 65uatom
// Element: 130uwasm
// Element: 65uatom
// Element: 130uwasm
