Crate cbpro

Coinbase pro client with latest Future and Stream traits support.

cbpro

This crate provides an easy to use Coinbase Pro binding interface. For private endpoints use AuthenticatedClient. For public endpoints use PublicClient or AuthenticatedClient::public. All methods beloging to the public or private client will return QueryBuilder<'a, T> which has split implementations per T. The final result of any operation be it methods from client or websocket-feed will resolve to serde_json::Value.

The public feed endpoint is also available via WebSocketFeed::connect or the private endpoint at WebSocketFeed::connect_auth.

Examples

Async Client

use cbpro::client::{PublicClient, SANDBOX_URL};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = PublicClient::new(SANDBOX_URL);
    let products = client.get_products().json().await?;
    println!("{}", serde_json::to_string_pretty(&products).unwrap());
    Ok(())
}

Async Pagination

use cbpro::client::{PublicClient, SANDBOX_URL};
use futures::TryStreamExt;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = PublicClient::new(SANDBOX_URL);
    let mut pages = client.get_trades("BTC-USD").paginate()?;

    while let Some(json) = pages.try_next().await? {
        println!("{}", serde_json::to_string_pretty(&json).unwrap());
        tokio::time::delay_for(core::time::Duration::new(1, 0)).await;
    }
    Ok(())
}

Async Websocket

use cbpro::websocket::{Channels, WebSocketFeed, SANDBOX_FEED_URL};
use futures::TryStreamExt;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut feed = WebSocketFeed::connect(SANDBOX_FEED_URL).await?;
    feed.subscribe(&["BTC-USD"], &[Channels::LEVEL2]).await?;

    while let Some(value) = feed.try_next().await? {
        println!("{}", serde_json::to_string_pretty(&value).unwrap());
    }
    Ok(())
}
