I was reading https://blog.rust-lang.org/2017/07/05/Rust-Roadmap-Update.html, which mentioned that the Rust compiler now has a mode to go through the motions of compiling and show errors, but without generating any code. This way you can do a much faster build while iterating until you have no compile errors, then do a single build with code generation once everything looks good.[...]
We already have it. use -o- and it'll disable codegen.
