What does this PR try to resolve?
via issue #15505, Cargo currently errors on
with a message about
expected a version string or a detailed dependencyIt doesn’t hint that you can depend on a workspace member. This PR updatescargoso that when you write dep = true, the error also suggests:How should we test and review this PR?
In a workspace crate’s Cargo.toml, add
Run
cargo buildand you should see the enhanced error with the two workspace hints.Additional information
Regarding support for int/float, we only need a special case for boolean because they’re the only values that get the
workspace hint. Everything else just uses the normal detailed dependency error
