rci is a wrapper over environment variables of some common continuous integration services (atm only travis and circle-ci). It can also be used to check if your tests are running in a CI environment (I use this to skip some tests in rsoundio).
rosc is an implementation of the Open Sound Control Specification in pure Rust (the link to the spec. is dead). There are already some other implementations, but rosc supports almost all OSC features, compiles with modern rust (1.0+) and is properly tested.
rsoundio is a binding for libsoundio, a cross-platform audio input/output C library. We already have bindings for PortAudio and SDL but libsoundio offers some benefits over them. If you’re interested what those benefits are take a look in the wiki.
There is still a lot to do and room for improvement, e.g. the binding for audio input is not implemented.
This was also the first time that I’ve written an FFI binding, so I would be really happy if someone with more experience in this domain could check this crate out and give me some comments/recommendations. Or even better, if someone would like to improve it and send me some pull requests.
Have a nice saturday, everyone!
