Question about building rust-htslib with conda-installed dependencies

[wm75]

I'm currently working on a bioconda recipe for a tool depending on rust-htslib.
I've got a working version, but it seems the rust compilation chain still pulls in lots of C sources, via hts-sys I guess, when, naively, I had envisioned that I could just specify the existing htslib conda package as a host requirement and have rust-htslib link to it.
What's your take on how a best-practice recipe requiring rust-htslib should be set up? @johanneskoester maybe?
... and connected to that, would it be of value to have a dedicated rust-htslib bioconda package that other recipes could depend on?

Hi. The other recipes on bioconda also use hts-sys this way, i.e. statically linked. Hence, adding htslib as a dependency would not help. However, one could of course try to enhance hts-sys such that it can also use a shared library. In that case the dependency would help. I think this would however require some code/setup changes there.
