Rust GSK 4 bindings

The project website is here.

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

GSK is an intermediate layer that isolates GTK from the details of the OpenGL or Vulkan implementation.

Minimum supported Rust version

Currently, the minimum supported Rust version is 1.70.



We recommend using crates from, as demonstrated here.

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

gsk = { git = "", package = "gsk4" }

Avoid mixing versioned and git crates like this:

# This will not compile
gdk = {version = "0.1", package = "gdk4"}
gsk = { git = "", package = "gsk4" }
