ObjCrust

A proof of concept for using Rust to create an iOS static library.

Requires Xcode 5 and the iOS 7 SDK.

Based on doublec/rust-from-c-example

Status

What works:

Rust code exposes simple functions for working with integers and floats, using values, pointers and structs.
Make file creates architecture-specific libraries for the simulator (i386) and devices (armv7 and armv7s).
Creates universal static library for linking in iOS binary.
iOS project builds and runs on simulator and devices.

What doesn't work:

Compiles without standard library (maybe try with rust-core?)
When running on Simulator: Functions that return structs with float members cause a crash (maybe related to issue #5744?)

Usage

git clone https://github.com/shilgapira/ObjCrust.git
cd ObjCrust/Rust
make
cd ../iOS
open ObjCrust.xcodeproj
Build and run in Xcode
