Is it possible to keep binary checksum unchanged if code unchanged?

Hi, all

I found that every time when I rebuild the cargo project, the binary checksum changed, even though I did not change any code. So are there any build parameters to output the same binary as before if the code not changed?

What you want is called reproducible build. It's not a trivial task but we're making progress.

Thanks. I think I'd better use version numbers.
