There was a problem hiding this comment.
I think this can also be expressed as if !crate_types.contains(&new_part)
Crate types from multiple sources appear to be deduplicated properly, but not deduplicated if they come from the command line arguments. At worst, this used to cause compiler failures when `--crate-type=lib,rlib` (the same as `--crate-type=rlib,rlib`, at least at the time of this commit) is provided and generate the output multiple times otherwise.
