This is a Rust wrapper for liquid-dsp. It does not rely on autotools, and compiles the library purely within Rust. I've also created a simple wrapper interface to make it more ergonomic to use with Rust, and to add memory safety.
However, I've only configured the build script to compile and generate bindings for the filter module, which I'm using to resample audio in my other project.
I'd be happy wrap the rest of the library if there is enough interest. Open an issue or pull request if you're interested!
