The subclass module documentation suggests the wrapper type is optional. Is it really?

[cjao]

The documentation on the subclass module provides a code listing which indicates that the glib::wrapper!{} portion is optional:

// Optionally, define a wrapper type to make it more ergonomic to use from Rust
glib::wrapper! {
    pub struct SimpleObject(ObjectSubclass<imp::SimpleObject>);
}

However, the ObjectSubclass trait of the implementation and the ObjectSubclassIs trait implemented by the wrapper! macro refer to each other.

trait ObjectSubclass {
    type Type: ObjectType + ObjectSubclassIs
    ...
}


trait ObjectSubclassIs {
    type Subclass: ObjectSubclass
    ...
}

Should the documentation be tweaked?

That documentation is outdated. This was the case long ago but not anymore.

Do you want to submit a PR for fixing this?

Was solved as part of #1885
