==========

A versatile websocket client that supports many cryptocurrency exchanges.

## Usage

```rust
use crypto_ws_client::{BinanceSpotWSClient, WSClient};

fn main() {
    let (tx, rx) = std::sync::mpsc::channel();
    let thread = std::thread::spawn(move || {
        for msg in rx {
            println!("{}", msg);
        }
    });
    let mut ws_client = BinanceSpotWSClient::new(tx, None);
    let channels = vec!["btcusdt@aggTrade".to_string(), "btcusdt@depth".to_string(),];
    ws_client.subscribe(&channels);
    ws_client.run(None);
    wc_client.close();
    drop(ws_client);
    thread.join().unwrap();
}
```

## Contribution

### How to add support for a new exchange

#### 1. Add a new file under `src/clients/`

Define a struct in the file, with the same name as the file.

Define a `channels_to_commands()` function which can convert raw channels to subscribe/unsubscribe commands.

Define a customized `on_misc_msg()` to handle misc messages.

Use `define_client!` macro to implement the `WSClient` trait.

#### 2. Add a new file under `tests/`

Add a new file under `tests/` and put some integration tests in it.
