rust-code-analysis-cli -m -p path/to/crate/src/lib.rs does nothing

When I run rust-code-analysis-cli -m -p path/to/crate/src/lib.rs , nothing happens.

According to rust-code-analysis-book/src/commands/metrics.md this should do something.

I am using master with #1084 applied.

I have got as far with debugging as verifying that fn metrics in spaces.rs is processing the Rust code, but func_space is always false even when there are fns in the file, and the nodes including some of type function_item so it looks like it is finding the fns.

My initial feedback is that it would be nice if the CLI reported something like "No functions found in files analysed".

Ok, the reason why I am getting no results is #1084 .
When I use #1086 , I get results.

Still, the CLI should give some sort of result if no fns were found.

Fixed by #1086.
