There was a problem hiding this comment.
I think probably we should say something like "in src/bootstrap/builder.rs" here, though I guess it's not that hard to find:
$ rg 'describe!'
src/bootstrap/builder.rs
494: Kind::Build => describe!(
525: Kind::Check => describe!(
536: Kind::Test => describe!(
591: Kind::Bench => describe!(test::Crate, test::CrateLibrustc),
592: Kind::Doc => describe!(
612: Kind::Dist => describe!(
640: Kind::Install => describe!(
654: Kind::Run => describe!(run::ExpandYamlAnchors, run::BuildManifest, run::BumpStage0),
So maybe alright for now, and better short for such a specific message anyway.
