Arrayfire Rust Bindings

This project is currently in it's infancy and there will be quite a few issues to work through.

Currently the example creates an arrayfire array structure and runs the code from helloworld except indexing operations.

Building & Running

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.

To build arrayfire:

git submodule update --init --recursive
cargo build

To run hello world example:

~/p/arrayfire_rust> cargo run --example helloworld
...
     running 1 test

Is u8_cnst array float precision type ? false

Issues

You might see something along the lines of :

dyld: Library not loaded: @rpath/libafopencl.3.dylib

This is related to this Rust issue A workaround for now is to add the location of libaf*.dylib to your LD_LIBRARY_PATH.
