Yahoo Finance for Rust

A Rust library for getting financial information from Yahoo!

• Historical OHLCV pricing information

use yahoo_finance::history;

fn main() {
   // retrieve 6 months worth of data for Apple
   let data = history::retrieve("AAPL").unwrap();

   // print the date and closing price for each day we have data
   for bar in &data {
      println!("On {} Apple closed at ${:.2}", bar.timestamp.format("%b %e %Y"), bar.close)
   }
}

• Realtime pricing information

use futures::{ future, StreamExt };
use yahoo_finance::Streamer;

#[tokio::main]
async fn main() {
   let mut streamer = Streamer::new(vec!["AAPL", "^DJI", "^IXIC"]);

   streamer.stream().await
      .for_each(|quote| {
         println!("At {}, {} is trading for ${} [{}]", quote.timestamp, quote.symbol, quote.price, quote.volume);

         future::ready(())
      })
      .await;
}

• Symbol profile information

use futures::{ future, StreamExt };
use yahoo_finance::Streamer;

#[tokio::main]
async fn main() {
   let mut streamer = Streamer::new(vec!["AAPL", "^DJI", "^IXIC"]);

   streamer.stream().await
      .for_each(|quote| {
         println!("At {}, {} is trading for ${} [{}]", quote.timestamp, quote.symbol, quote.price, quote.volume);

         future::ready(())
      })
      .await;
}
