Crate gdk4

Rust GDK 4 bindings

The project website is here.

Rust bindings of GDK 4, part of gtk4-rs.

Minimum supported Rust version

Currently, the minimum supported Rust version is 1.70.

Documentation

• The Rust API Stable/Development
• The C API
• GTK Installation instructions

Using

We recommend using crates from crates.io, as demonstrated here.

If you want to track the bleeding edge, use the git dependency instead:

[dependencies]
gdk = { git = "https://github.com/gtk-rs/gtk4-rs.git", package = "gdk4" }

Avoid mixing versioned and git crates like this:

# This will not compile
[dependencies]
gtk = {version = "0.1", package = "gtk4"}
gdk = { git = "https://github.com/gtk-rs/gtk4-rs.git", package = "gdk4" }
