error: Could not compile `scirust`.

UPD: build fails with the package version, published on crates.io; git version compiles successfully

Hi,

I haven't updated the published version on crates.io yet. I actually did a refactoring recently in which I split the library into multiple sub-libraries. Now, the crates.io requires all sub-libraries to be registered separately on their database. I haven't done that yet. That's why, I couldn't update the main library on crates.io either. I am still wondering if it makes sense to publish all the individual sub-libraries separately on crates.io.

You can see the library dependency structure from the toml files.
