# RivalzClient

RivalzClient is a Rust client for interacting with the Rivalz API. This client allows you to upload files to IPFS and retrieve their IPFS hash.

## Features

- Upload files using multipart form data.
- Retrieve the IPFS hash of uploaded files.
- Robust error handling for network issues, server errors, and file accessibility.

## Getting Started

### Prerequisites

- [Rust](https://www.rust-lang.org/tools/install) (version 1.50 or later)
- A Rivalz API secret token.

### Installation

To use the `RivalzClient` library in your project, add the following to your `Cargo.toml`:

```toml
[dependencies]
rivalz_client = "0.1.0"
```

### Usage

1. **Set your Rivalz API secret token as an environment variable**:

    ```sh
    export SECRET_TOKEN="your_secret_token"
    ```

2. **Create an instance of `RivalzClient` and use it to upload a file**:

    ```rust
    use rivalz_client::RivalzClient;

    fn main() {
        let client = RivalzClient::new(None);
        let file_path = "path/to/your/file.txt";
        
        match client.upload_file(file_path) {
            Ok(ipfs_hash) => println!("File uploaded successfully! IPFS hash: {}", ipfs_hash),
            Err(e) => eprintln!("Failed to upload file: {}", e),
        }
    }
    ```
