For example, when writing this piece of code:
pub struct FinvizHelper{
signal: SignalType,
order: OrderType,
}
impl FinvizHelper{
pub async fn get(&self) -> Result<(),Box<dyn std::error::Error>> {
Screener::new(ScreenerType::Overview)
.set_signal(self.signal)
.set_order(self.order)
.scrape().await?
.to_csv_file("output.csv")?;
Ok(())
}
}
The members self.signal
and self.order
are not copyable because their matching types are not copyable, therefore there's implicit move, but the required behavior here is copy.
Solution:
change current #derive
of SignalType
, OrderType
to #[derive(Copy, EnumIter)]
The error occurs because of parsing error of table elements
Error: "Cannot find News table"
On finviz it is possible to sort stocks not only by ascending order, but also by descending order.
Solution:
OrderType::Ticker => "o=ticker",
===>
OrderType::TickerAsc => "o=ticker",
OrderType::TickerDesc => "o=-ticker",
(should be done for all OrderTypes)
