plan to publish new version after land this

[vitiral]

Looks great, much better than copy/paste! Thanks for pushing this past the finish line :)

My only comment would be to include a doc-comment at the top of util/lib.rs to say why it exists.

@vitiral
looks like cargo doesn't support publishing crates with internal crates according to rust-lang/cargo#1565
any suggestions besides publishing this internal crate shared by source and build script?

[vitiral]

It looks like the only solution is to publish the library crate separately.

There might actually be some value to that in this case, as someone might want to create different tables but not depend on this crate. Would it be too much to publish a crc-core crate or something and then depend on it?

I'm sorry, I could have sworn I saw a crate that used a path dependency work. Obviously I was mistaken.

[mrhooray]

That's fine. Just wanted to check in case we have alternatives.
