Why this Fork?

In rust_q_sim I am using metis-rs as a dependency. Since this crate is a Binding to the Metis-C-Library, the metis-sys crate has a dependency on bindgen v0.58. The rust_q_sim project also has a dependency on the rsmpi crate which itself is a wrapper for the MPI-C api. This project also uses bindgen but with v0.60. This version conflict resulted in build errors, where libclan wasn't loaded correctly. With this fork I changed the libgen dependency to v0.60 to match the one in rsmpi. I didn't make a PR into the upstream repository, since the current version of bindgen is v0.63 which means both, metis-rs and rsmpi are using outated versions. Since the metis-rs repo is quite stable I would think that this is ok for now.

Idiomatic bindings to libmetis, a graph and mesh partitioner.

Building

Prerequisites:

• METIS
• clang v3.9 or above

Bindings to METIS are made on the fly. If METIS is installed in a non-standard location, please use the following commands:

export METISDIR=path/to/your/metis/installation
export CPATH="$METISDIR/include"
export RUSTFLAGS="-L$METISDIR/lib"

The environment variable $METISDIR must point to a directory containing a lib/ and a include/ directory containing the shared libraries and the headers of METIS, respectively.

Once these variables are set, you can build the bindings with cargo build.

Build the documentation

If your METIS installation lies in a non-standard path, you will need to set the RUSTDOCFLAGS environment variable to build the documentation:

export RUSTDOCFLAGS="-L$METISDIR/lib"

Then you can call cargo doc --no-deps --open.
