In #116 we're hit problems where the dylib still exists but the cargo project was deleted. Currently, the install process is skipped if just the dylib file exists. After the install we call
cargo metadata
to resolve the toolchain version, which will error if the project was deleted. With this PR, we also detect the project being deleted and do a rebuild, not just when the dylib is missing.Long-term it would probably be better to just store the toolchain version in a metadata json or text file, and not reresolve it each time. With #117 currently refactoring much of cargo-gpu, I think we'll wait for that to complete before implementing it.
