//! Background worker for fetching AUR package comments.

use tokio::sync::mpsc;

use crate::sources;
use crate::state::types::AurComment;

/// What: Spawn background worker for AUR comments fetching.
///
/// Inputs:
/// - `comments_req_rx`: Channel receiver for comments requests (package name as String)
/// - `comments_res_tx`: Channel sender for comments responses
///
/// Output:
/// - None (spawns async task)
///
/// Details:
/// - Listens for package name requests on the channel
/// - Fetches comments asynchronously using `fetch_aur_comments`
/// - Sends results as `(String, Result<Vec<AurComment>, String>)` matching PKGBUILD pattern
/// - Handles errors gracefully (sends error message instead of panicking)
