Your crate is BROKEN

Your crate rust-criu does not have the correct dependency requirement for protobuf:
Cargo.toml:13:

protobuf = "3.2.0"

This is fatal as this WILL bring build errors on anything that depends on your crate once a newer version of protobuf is available.

Solution

Specify the version for protobuf exactly:

protobuf = "= 3.2.0"

and consider yanking previous versions of this crate. (All of them break anyway.)

And plus, now you can safely remove rust_criu_protobuf/rpc.rs:26 knowing that the protobuf version is definitely 3.2.0.

What do you think?

Unfortunately, now it seems failed.
#9

See build logs: https://docs.rs/crate/rust-criu/0.2.0/builds/579956

I believe this is because build.rs is unconditionally generating protobufs and the output is being written to a read-only path.
If that is the problem, would it make sense to have a separate create feature for generating protos?

Hey, currently the errors that occur when operating are reported as are, without any additional context information. It would be better for debugging and development purposes if this provided more information.
I would be happy to open a PR with the changes, but I am considering using anyhow crate to provide context in error messages. Would this project be fine with adding that as a dependency to provide better error context?

Thank you :)
