[Concept] : [Q] Crate : Godot Extension

[h0lybyte]

Core Concept/Theory
We would need a clear and concise description of the concept. For example, It would be cool if [...]

It would be cool if Q could serve as a lightweight, all-in-one toolkit for Rust developers to extend Godot functionality, seamlessly integrating game management, audio handling, ECS architecture, and multi-threading into a single crate."

---

Alternative Ideas
Is there any other way this concept could be used?

Q could also be adapted as a modular framework, allowing developers to opt-in to specific features (e.g., just the Music Manager or Bevy ECS) instead of using the full suite, or extended to support additional Godot features like physics or UI management.

---

Alternative Examples/Sources
Are there any other references that you can provide?

Similar projects include the Godot Rust GDExtension examples (https://github.com/godot-rust/gdextension), Bevy Engine’s ECS approach (https://bevyengine.org/), and Tokio’s async runtime documentation (https://tokio.rs/). These could inspire further refinements or integrations for Q.

---

Additional information
Add any other context or examples of this concept here.

The Q crate is designed for developers familiar with Rust and Godot, aiming to reduce boilerplate code and improve performance. An example use case: managing a multiplayer game loop with Tokio while using Bevy ECS for entity updates, all within Godot’s ecosystem.

Rust Application Notes

TODO (1): Remove the extra String allocation:

  pub fn get(&self, key: &str) -> Option<Gd<T>> {
    self.map.pin().get(&key.to_string()).cloned()
  }

  pub fn get_arc(&self, key: &str) -> Option<Arc<Gd<T>>> {
    self.map
      .pin()
      .get(&key.to_string())
      .map(|gd| Arc::new(gd.clone()))
  }

  pub fn contains(&self, key: &str) -> bool {
    self.map.pin().contains_key(&key.to_string())
  }

The to_string() is not needed.

For the string conversion

godot-rust/gdext#1062

Good to keep a reference of that for the future ^

Updated the extension to use v0.2.4 of GDExt and then fixing the user_data.rs to no longer use guards but rather pins.
