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?)
