GLib bindings for Rust.
Alongside GLib bindings, this crate also includes the infrastructure to subclass
GObject for extending libraries like GTK+. A code example can be found in the documentation of this crate in the
This library contains
bindings to some essential GLib, GObject, GIO types and APIs,
common building blocks used in both handmade and machine generated bindings to GTK+ and other GLib-based libraries.
It is the foundation for higher level libraries with uniform Rusty (safe and strongly typed) APIs. It avoids exposing GLib-specific data types where possible and is not meant to provide comprehensive GLib bindings, which would often amount to duplicating the Rust Standard Library or other utility crates.
The library is a work in progress: expect missing functionality and breaking changes.

Each class and interface has a corresponding smart pointer struct representing an instance of that type (e.g.
GtkWidget). They are reference counted and feature interior mutability similarly to Rust's
Rc<RefCell<T>> idiom. Consequently, cloning objects is cheap and their methods never require mutable borrows. Two smart pointers are equal iff they point to the same object.
Interfaces and non-leaf classes also have corresponding traits (e.g.
gtk::WidgetExt), which are blanketly implemented for all their subtypes.
You can create new subclasses of
Object or other object types. Look at the module's documentation for further details and a code example.
GLib-based libraries largely operate on pointers to various boxed or reference counted structures so the bindings have to implement corresponding smart pointers (wrappers), which encapsulate resource management and safety checks. Such wrappers are defined via the
glib_wrapper! macro, which uses abstractions defined in the
translate module defines and partly implements conversions between high level Rust types (including the aforementioned wrappers) and their FFI counterparts.
