A tour on newest and future developments for gtk-rs, the Rust bindings to GTK+. Agenda Introduction: Small presentation of Gtk-rs project. Small code demonstration. Last year developments: Add of futures to handle asynchronous function calls. Generation of union types. A lot of new types/functions generated. Next developments: Generate bindings for functions/methods taking callbacks as argument. Long run: being able to "subclass" widgets. Global API improvements as always! Generate sys crates documentation on gtk-rs.org as well? gtk-rs ecosystem: A lot of projects are starting to use gtk-rs, two of them are part of the ten most active GNOME projects on gitlab. Some (nice) API are built upon it like relm. Question time!
