I've been able to replicate this with prost. I've had to fork off their repo to apply a branch that added some needed introspection for using the Any
type. Unfortunately, as soon as I pointed cargo raze at the new repo, it keeps on trying to build the crate at the root instead of the sub-packages. I've been able to confirm this is what's happening by looking at the generated bazel files and, sure enough, both the targets and the download are using the whole repo. There's a surprising number of crates that do this kind of split within the same repo, mostly ones with a main and a sys crate, but also ones with one package for use in build scripts like the aformentioned prost. This does make using these libraries quite difficult without doing things like setting up our own crates registry.
This is similar - perhaps a dupe of #399
Background: cargo does not permit specifying a crate in git in a git repository that uses workspace configuration; instead the whole workspace is specified, and then cargo picks out the desired crate by introspection.
Consider this example: example.zip
This uses the protobuf and protoc-rust crates, but fails at compile time:

FAILED: Build did NOT complete successfully ```I'm not 100% sure - still learning bazel - but I think what is happening is that the protobuf-test crate build.rs is being compiled instead of the protobuf crate build.rs. I think this because if you look at the -test build.rs, it outputs build instructions for that file that is being complained about.
(Note - I didn't add local targets as they aren't needed to show the problem.
bazel query ...:*
-bazel build @raze__protoc_rust__3_0_0_pre//:protoc_rust
will fail with the correct error)
