You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: track_table.rs
    path of file: ./repos/spotify-tui/src/handlers
    
    the code of the file until where you have to start completion: use super::{
  super::app::{App, RecommendationsContext, TrackTable, TrackTableContext},
  common_key_events,
};
use crate::event::Key;
use crate::network::IoEvent;
use rand::{thread_rng, Rng};
use serde_json::from_value;

pub fn
    
fn handle_recommended_tracks(app: &mut App) {
  let (selected_index, tracks) = (&app.track_table.selected_index, &app.track_table.tracks);
  if let Some(track) = tracks.get(*selected_index) {
    let first_track = track.clone();
    let track_id_list = track.id.as_ref().map(|id| vec![id.to_string()]);

    app.recommendations_context = Some(RecommendationsContext::Song);
    app.recommendations_seed = first_track.name.clone();
    app.get_recommendations_for_seed(None, track_id_list, Some(first_track));
  };
}
