Hi, I'm the developer of Rune. In this project, Dart is primarily used for the GUI, while Rust handles all data-related operations. As you mentioned, Dart's performance and ecosystem are sufficient for most tasks in a typical music player. However, Rune includes some complex features that challenge Dart's ecosystem and performance, such as media recommendation.

Rune has a built-in media analysis and recommendation system. It extracts dozens of acoustic features from audio, creating a high-dimensional space. Searching for nearby points in this space helps listeners find similar tracks, offering features akin to those on streaming platforms.

While creating a traditional audio player is an option, I wanted to explore something new. That's why I chose Rust for its performance and ecosystem advantages.

Regarding the inter-operation between Dart and Rust, I used a library called `rinf`. They communicate via protobuffer by sending signals to each other, and the experience has been quite smooth.
