This is a basic Rust API for OpenSpiel. Please note that it is currently experimental and may not work as expected. If you use it, please report any issues. Fixes and improvements are more than welcome!

See the CMakeLists.txt to see how it is setup: a dynamic shared library is created similarly to python extension (librust_spiel.so). A simple rust crate is created in this directory using cargo build and a simple example is run using cargo as well. Note that currently LD_LIBRARY_PATH must include the location of the dynamic library so that it gets properly loaded at run time.

Note: this API currently only supports turn-based games. To support simultaneous-move games, several API functions would need to be added, such as legal actions for specific players, observation and information state tensors for specific players, and apply action for joint actions.
