The lcov file exists according to ls. It was produced by grcov but your action doesn't indicate any parsing errors so I guess it is correct. There's no official information on how to support Rust so I'm using grcov's docs and a bit of guessing to make things work. The error seems to be related to convertLcovToCoveralls but there isn't a way to directly upload the coveralls JSON file produced by grcov (#104).
