Should generate deprecate warning in rust code, when C code macro expand to `__attribute__` `__deprecated__`

[loynoir]

reproduce

C code

GDK_DEPRECATED_IN_4_10_FOR(gtk_widget_set_visible or gtk_window_present)
void       gtk_widget_show 

__attribute__((__deprecated__("Use '" "gtk_widget_set_visible or gtk_window_present" "' instead"))) extern
void       gtk_widget_show 

actual

rust code

// This file was generated by gir (https://github.com/gtk-rs/gir)
// from gir-files (https://github.com/gtk-rs/gir-files)
// DO NOT EDIT

    pub fn gtk_widget_should_layout(widget: *mut GtkWidget) -> gboolean;
    pub fn gtk_widget_show(widget: *mut GtkWidget);
    pub fn gtk_widget_size_allocate(

expected

Deprecate warning when use rust gtk4_sys::gtk_widget_show

[bilelmoussaoui]

the deprecated attribute is only generated for the safe api wrapper

@bilelmoussaoui

I use rust as modern C.

Would be nice to receive deprecation within gtk4_sys::gtk_widget_show

Seems like a good idea to have that in gir, but less important than for the safe API. Do you want to provide a PR for this? The information about deprecations is already available in the code generator, just not made use for when generating the -sys bindings.

[loynoir]

I think, instead of

• change every downstream build script

should

• let upstream gir options default to generate deprecation

In my option,

• With deprecation mapping, will be 1:1 mapping.

[sdroege]

Yes that's what I'm saying. Do you want to provide a PR for that?

[loynoir]

Sorry, willing to, but sticking with something else.
