# aria2-ws

An aria2 websocket jsonrpc in Rust.

Built with `tokio`.

[Docs.rs](https://docs.rs/aria2_ws)

[aria2 RPC docs](https://aria2.github.io/manual/en/html/aria2c.html#methods)

[Changelog](./CHANGELOG.md)

## Features

- Methods and typed responses
- Auto reconnect
- Ensures `on_download_complete` and `on_error` callback to be executed even after reconnected.
- Notification subscription

## Example

```rust
use std::sync::Arc;

use aria2_ws::{Client, Callbacks, TaskOptions};
use futures::FutureExt;
use serde_json::json;
use tokio::{spawn, sync::Semaphore};

async fn example() {
    let client = Client::connect("ws://127.0.0.1:6800/jsonrpc", None)
        .await
        .unwrap();
    let options = TaskOptions {
        split: Some(2),
        header: Some(vec!["Referer: https://www.pixiv.net/".to_string()]),
        // Add extra options which are not included in TaskOptions.
        extra_options: json!({"max-download-limit": "100K"})
            .as_object()
            .unwrap()
            .clone(),
        ..Default::default()
    };

let mut not = client.subscribe_notifications();
    spawn(async move {
        loop {
            match not.recv().await {
                Ok(msg) => println!("Received notification {:?}", &msg),
                Err(broadcast::error::RecvError::Closed) => {
                    println!("Notification channel closed");
                    break;
                }

                }
            }
        }
