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 install the binary into $PATH, or you can provide the binary location explicitly like:
capnp compile -o/path/to/capnpc-rust src/schema/user.capnp I don't think there's a mailing list specifically for the Rust implementation but you could try filing issues on the github repo. -Kenton On Thu, Aug 31, 2023 at 7:48 AM Tanguille Grootaert < tanguille.groota...@gmail.com> wrote: > 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.
