Original link: Cutting Down Rust Compile Times From 30 to 2 Minutes With One Thousand Crates / Feldera blog.
I am not a Rust guy, but I find it difficult to consider compile time a real problem. Given how long time that it takes to produce the code and how long time it takes to run the unit tests after every build, then I don't see compile time as a huge issue.
25 minutes? Start it and do something productive while it runs!
