How can i set the Priority of unix_fd_add_local? i see no API for that.

[ogios]

inside it:

#[doc(alias = "g_unix_fd_add_full")]
pub fn unix_fd_add_local<F>(fd: RawFd, condition: IOCondition, func: F) -> SourceId
where
    F: FnMut(RawFd, IOCondition) -> ControlFlow + 'static,
{
    unsafe {
        let context = MainContext::default();
        let _acquire = context
            .acquire()
            .expect("default main context already acquired by another thread");
        from_glib(ffi::g_unix_fd_add_full(
            ffi::G_PRIORITY_DEFAULT,
            fd,
            condition.into_glib(),
            Some(trampoline_unix_fd_local::<F>),
            into_raw_unix_fd_local(func),
            Some(destroy_closure_unix_fd_local::<F>),
        ))
    }
}

and there's no unix_fd_add_local_full, and unix_fd_source_new needs Send.

i need to set it's priority to LOW because i meet an issue where queue_redraw() does not function when too many unix_fd_add_local exists at the same time.

[ogios]

it says that the priority of redraw is HIGH + 20: https://docs.gtk.org/glib/const.PRIORITY_HIGH_IDLE.html

weird...

EDIT: OH NO, it's HIGH_IDLE(100) + 20, and DEFAULT which we used here is 0. SO it is indeed a priority issue

[ogios]

ok, after forking a bunch of things and managed to deal with a lot of version issues...
i added this: ogios@1bcef08

and it works perfectly, issue sloved.

but i can not maintain

• ogios/gtk4-rs
• ogios/gtk4-layer-shell-gir
• ogios/gtk-rs-core

all by myself, i'll be grateful if unix_fd_add_full_local can be added here

#1614 got merged, wait until a release then
