I (a random Rust/C Cap'n Proto user) started helping Tanguille on the
Discord and then saw their emails here, so I'll reply here in case
others find it in a search.

Even though we accounted for what was happening here, just for f
I finally got it working. The main problem was that I didn't understand
that the build file automated the capnpc process and that I needed to
understand that capnp disables the use of the std lib. There are still some
problems.
The build seems to have worked when I use the absolute path, while
It may help to read some of the examples for capnproto-rust:

Using "cargo build" with a build.rs file is the normal way to compile your
.capnp files for Rust.

When you run `capnp compile -orust`, the `capnp` tool will attempt to
execute a binary `capnpc-rust` from your $PATH. This binary seems to be
provided by the capnpc crate, but declaring a dependency on the crate
probably does not automatically install it into your $PATH. You can either

That can't be the issue since my depedencies are containing the same ones
as the examples in that repo, where `capnp` and `capnpc` are a part of. The
code compiles so the dependencies are valid. Only thing I can think about
is that the apt repo has outdated binaries for the Cap'n Proto compiler
You need to install the Rust capnp plugin. I'm not very familiar with Rust
but it looks like this is provided by the crate called `capnpc`.

Thanks for the explanation Kenton. Cool to see you're still so involved,
it's an honor to get an answer from you.
I am now trying to implement it in a little testproject with rust. However
I can't seem to figure out how to install `capnpc-rust`. I installed both
`capnproto` and `libcapnp-dev` v
Hi Tanguille,
Cap'n Proto is agnostic to the underlying byte transport. It can layer on
top of any byte stream or datagram stream. In terms of the C++
implementation, you can write a custom implementation of the
capnp::MessageStream interface in terms of any transport you'd like. For
example, you
