Pass a custom struct needed for callback as a custom object property

Hello, I’m struggling to find an answer online and I’m pretty new to rust.

I’m currently trying to build a custom object with a toggle as a child. The toggle needs to use datas that are stored in a custom struct. The issue I’m facing is that this struct is instantiated from a library that I built which does not include GTK and .property requires a glib value.

So this is where i’m struggling :

use my_lib::MyCustomStruct;

impl CustomObject {
    pub fn new(label1: &str, status: bool, label2: &str, custom_struct: MyCustomStruct) -> Self {
        Object::builder()
            .property("label1", label1)
            .property("status", status)
            .property("label2", label2)
            .property("custom-struct", custom_struct)
            .build()
    }
}

But here’s the error I’m facing : the trait bound `Value: From` is not satisfied

So I assume I have to implement a From for glib::Value, but I feel kind of lost there. I don’t really know where to go from there, because whenever I type something like this, I have other errors caused by the fact that the struct is not defined in the current crate.

For a better understanding, I need data stored in MyCustomStruct because they are used to build paths to items. These are 2 String and 2 Option.

Am I missing something? Is there a fix or a workaround?

Thank you for the time spent reading & answering me!
