generate_rust fails in GitHub Actions with io error

[Zk2u]

Having issues with a GH Action running Planus. It installs with Cargo. planus check runs okay.

It's failing somewhere in here:

planus/crates/planus-codegen/src/lib.rs

Line 30 in be40ee0

pub fn generate_rust(declarations: &Declarations) -> Result<String, CodegenError> {

I am not sure if we have enough context to diagnose this. Can you run it with RUST_BACKTRACE=1 as suggested?

This is definitely a bug in terms of error reporting on our side.

I think the underlying issue might be that you do not have rustfmt installed in the CI environment. Could you verify whether that is the case?

[Zk2u]

Can confirm that it was because rustfmt wasn't installed. All working now. We can open a new issue and reference this to fix the error reporting here.
