Download Client

New Download Client: $ARGUMENTS

You are adding a new download client integration for $ARGUMENTS to pir9.

Reference Files

Read these first to understand existing patterns:

• src/core/download/clients.rs — trait definition and existing implementations
• src/core/download/ — directory listing for all client modules
• src/api/v5/download_client.rs — API endpoints for client management

Steps

1. Implement the DownloadClient trait

Create a new module in src/core/download/ for the client:

#[async_trait::async_trait]
pub trait DownloadClient: Send + Sync {
    fn name(&self) -> &str;
    fn protocol(&self) -> DownloadProtocol;  // Usenet or Torrent
    async fn test(&self) -> Result<()>;
    async fn add_from_url(&self, url: &str, category: &str) -> Result<String>;
    async fn add_from_file(&self, data: &[u8], filename: &str, category: &str) -> Result<String>;
    async fn get_downloads(&self) -> Result<Vec<DownloadStatus>>;
    async fn remove(&self, id: &str) -> Result<()>;
}
