disable jobserver on unix, if file descriptors are negative by belovdv · Pull Request #68 · rust-lang/jobserver-rs (original) (raw)

With separated NegativeFd error kind, which has extensive comment I'd expect to see more explanations of what CannotParse error means and why doesn't it follow manual:

If your tool does not recognize the format of the --jobserver-auth string, it should assume the jobserver is using a different style and it cannot connect.

Not a part of this PR, though
