11 months ago I have a similar issue except everything is in the same crate.
I would like to be able to import a protofile into another.
Compiling and accessing the members of each protocol sepparately works fine, but they cannot access eachother:

}I had similar issues in golang when importing a package because I was using relative package names imports and go doesn't allow that in modules. So I was forced to specify a fully qualified package name in the option go_package and make a library that my other go modules could then import the grpc functionality from.

Description
Hi people! Thanks for your amazing work!
I have this dir structure:
as you can see I have many crates under
cratesdir and I have acommon.protowhich I would like to import in my crates.I'm using a
build.rsfor each crate because I cannot (right?) use one for the entire Cargo workspace (I tried: Cargo doesn't start build.rs in workspace root dir).So I'm trying to import common.proto in file like this:
and in my VSCode this is working.
But when I start
build.rsthrows with:My
build.rsis:How can I fix this?
