### Move to Examples Directory

Source: https://github.com/backpack-exchange/bpx-api-client/blob/master/README.md

Command to change the current directory to the examples folder within the Rust client. This is typically done after building.

```bash
cd examples
```

### Install Just Build Tool

Source: https://github.com/backpack-exchange/bpx-api-client/blob/master/README.md

Command to install the 'just' build tool using Cargo, the Rust package manager. This tool is used for simplifying build tasks.

```bash
cargo install just
```

### REST API Example - Get Open Orders

Source: https://github.com/backpack-exchange/bpx-api-client/blob/master/rust/client/README.md

A Rust example demonstrating how to initialize the BpxClient and fetch open orders for a specific symbol using the REST API. It handles environment variables for base URL and secret key, and prints the orders or errors.

```rust
use bpx_api_client::{BpxClient, BACKPACK_API_BASE_URL};
use std::env;

#[tokio::main]
async fn main() {
    let base_url = env::var("BASE_URL").unwrap_or_else(|_| BACKPACK_API_BASE_URL.to_string());
    let secret = env::var("SECRET").expect("Missing SECRET environment variable");

    let client = BpxClient::init(base_url, secret, None)
        .expect("Failed to initialize Backpack API client");

    match client.get_open_orders(Some("SOL_USDC")).await {
        Ok(orders) => println!("Open Orders: {:?}", orders),
        Err(err) => tracing::error!("Error: {:?}", err),
    }
}
```

### WebSocket API Example - Subscribe to RFQs

Source: https://github.com/backpack-exchange/bpx-api-client/blob/master/rust/client/README.md

A Rust example showing how to initialize the BpxClient with WebSocket support and subscribe to Request For Quote (RFQ) streams. It uses channels to receive and print RFQ messages.

```rust
use anyhow::Result;
use bpx_api_client::{BpxClient, BACKPACK_API_BASE_URL, BACKPACK_WS_URL};
use bpx_api_types::rfq::RequestForQuote;
use std::env;
use tokio::sync::mpsc;

#[tokio::main]
async fn main() -> Result<()> {
    let base_url = env::var("BASE_URL").unwrap_or_else(|_| BACKPACK_API_BASE_URL.to_string());
    let ws_url = env::var("WS_URL").unwrap_or_else(|_| BACKPACK_WS_URL.to_string());
    let secret = env::var("SECRET").expect("Missing SECRET environment variable");

    let client = BpxClient::init_with_ws(base_url, ws_url, &secret, None)?;

    let (tx, mut rx) = mpsc::channel::<RequestForQuote>(100);
    tokio::spawn(async move {
        while let Some(rfq) = rx.recv().await {
            println!("Received RFQ: {:?}", rfq);
        }
    });

    client.subscribe_to_rfqs(tx).await;

    Ok(())
}
```

### Navigate to Rust Folder

Source: https://github.com/backpack-exchange/bpx-api-client/blob/master/README.md

Command to navigate to the Rust directory within the project. Assumes the user is in the project root.

```bash
cd rust
```

--------------------------------

### Build All Rust Packages

Source: https://github.com/backpack-exchange/bpx-api-client/blob/master/README.md

Command to build all packages within the Rust client using the 'just' build tool. This compiles the entire Rust project.

```bash
just build
```

--------------------------------

### Run Development Tasks with Just

Source: https://github.com/backpack-exchange/bpx-api-client/blob/master/rust/client/README.md

Shows how to use the 'just' command-line tool to manage build and development tasks for the project. Running 'just' without arguments lists available commands.

```shell
just
```

### Enable WebSocket Support in Cargo.toml

Source: https://github.com/backpack-exchange/bpx-api-client/blob/master/rust/client/README.md

Demonstrates how to enable the 'ws' feature for the bpx_api_client crate in Cargo.toml to include WebSocket functionality.

```toml
[dependencies]
bpx_api_client = { version = "x.y.z", features = ["ws"] }
```

--------------------------------

### Add bpx_api_client to Cargo.toml

Source: https://github.com/backpack-exchange/bpx-api-client/blob/master/rust/client/README.md

Specifies how to add the bpx_api_client crate as a dependency in a Rust project's Cargo.toml file.

```toml
[dependencies]
bpx_api_client = "x.y.z" # Replace with the latest version
```
