ArrayFire is a high performance library for parallel computing with an easy-to-use API. It enables users to write scientific computing code that is portable across CUDA, OpenCL and CPU devices. This project provides Rust bindings for the ArrayFire library. Given below table shows the rust bindings compatability with ArrayFire. If you find any bugs, please report them here.

Only, Major & Minor version numbers need to match.

You can find the most recent updated documentation here.

Linux, Windows and OSX. Rust 1.15.1 or higher is required.

To use the rust bindings for ArrayFire from crates.io, the following requirements are to be met first.

1. Download and install ArrayFire binaries based on your operating system.
2. Set the evironment variable AF_PATH to point to ArrayFire installation root folder.
3. Make sure you add the path to library files to your path environment variables.
   • On Linux & OSX: do export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$AF_PATH/lib
   • On Windows: Add %AF_PATH%\lib to your PATH environment variable.
4. Add arrayfire = "3.5.0" to the dependencies section of your project's Cargo.toml file - 3.5.0 is the lastest version of crate.

Once step (4) is over, you should be able to use ArrayFire in your Rust project. If you find any bugs, please report them here.

Edit build.conf to modify the build flags. The structure is a simple JSON blob. Currently Rust does not allow key:value pairs to be passed from the CLI. To use an existing ArrayFire installation modify the first three JSON values. You can install ArrayFire using one of the following two ways.

• Download and install binaries
• Build and install from source

To build arrayfire submodule available in the rust wrapper, you have to do the following.

git submodule update --init --recursive
cargo build

This is recommended way to build Rust wrapper since the submodule points to the most compatible version of ArrayFire the Rust wrapper has been tested with. You can find the ArrayFire dependencies below.

• Linux dependencies
• OSX dependencies

let num_rows: u64 = 5;
let num_cols: u64 = 3;
let dims = Dim4::new(&[num_rows, num_cols, 1, 1]);
let a = randu::<f32>(dims);
af_print!("Create a 5-by-3 matrix of random floats on the GPU", a);

~/p/arrayfire_rust> cargo run --example helloworld
