Publish a bazel-built crate on crates.io?

[Filip Filmar]

Hi folks!

Are there rules that allow publishing bazel-built crates to crates.io, by any chance?

Maybe I should be looking at https://github.com/liftedinit/many-rs/issues/143?

Hi! rules_rust maintainer here - I'm not aware of any rules to do so, but https://github.com/bazelbuild/rules_rust/issues/458 tracks rules_rust support.

Happy to discuss approaches and review PRs, if you're interested in contributing :)

The whole Cargo ecosystem (including crates.io) does not support distributing binary crates. Rust doesn't have a stable ABI either, so there really aren't any paths towards it. I think you're going to have to support building your crate with Cargo to publish it to crates.io.

On approaches, I suppose the baseline of presenting the crate source to `cargo` as if it were a rust project could be a baseline. Don't know what else is required.

I wrote up some thoughts on https://github.com/bazelbuild/rules_rust/issues/458#issuecomment-1663627425 - hopefully this is helpful!
