Function try_save 

pub fn try_save<T>(
    obj: &Gd<T>,
    path: impl AsArg<GString>,
) -> Result<(), IoError>
where
    T: Inherits<Resource>,

Saves a Resource-inheriting object into the file located at path.

This function can fail if ResourceSaver can’t save the resource to file, as it is a simplified version of ResourceSaver::save(). The underlying method can be used for more advances scenarios.

Note

Target path must be presented in Godot-recognized format, mainly the ones beginning with res:// and user://. Saving to res:// is possible only when working with unexported project - after its export only user:// is viable.

Example

use godot::prelude::*;

#[derive(GodotClass)]
#[class(base=Resource, init)]
struct SavedGame {
  // Exported properties are saved in `.tres` files.
  #[export]
  level: u32
};

let save_state = SavedGame::new_gd();
let res = try_save(&save_state, "user://save.tres");

assert!(res.is_ok());
