objrs demo

This demo of objrs is written in 100% Rust. It uses objrs to compile to machine code that is ABI-compatible with Objective-C, allowing it to utilize native Objective-C frameworks (e.g. AppKit, Foundation, Metal, MetalKit, etc.) without any intermediary FFI bridges.

When run, the application will open a window that uses Metal to render the Rust logo. Moving your mouse across this logo will interactively distort it.


  • A recent version of macOS (only macOS 10.13.6 has been tested).
  • Nightly Rust compiler (tested on rustc 1.30.0-nightly (b2028828d 2018-08-16)).


Just cargo run to run the demo app. Running the latest version of the demo can be done as follows:

git clone https://gitlab.com/objrs/objrs.git
cd objrs/demo
cargo run

The demo is also published on crates.io under the name objrs_demo.
