Panicking in a method will make godot report that the method does not exist

[lilizoey]

Using this code:

use godot::prelude::*;

#[derive(GodotClass)]
#[class(init, base=Node)]
pub struct Mini {
    #[base]
    base: Base<Node>,
}

#[godot_api]
impl Mini {
    #[func]
    fn bar(&self) {
        panic!("error")
    }
}

struct Testing;

#[gdextension]
unsafe impl ExtensionLibrary for Testing {}

if you attempt to call bar from gdscript, Godot will report that the method does not exist at runtime:

However it will also properly report the error we print:

Note that this does not seem to have any impact outside of run-time.

If Godot interprets failed functions calls as "function does not exist", is there realistically something that we can do on our side?

Should we just let the call succeed but still print an error? But then we'd need to return something fitting the signature... and this might have other negative effects?
