"Ok(result) => {" not a tuple struct or tuple variant from embuild

[JasonKleban]

In this repo, having followed the steps in my readme.md, I'm getting these errors about the Result type in embuild source. Any help please?

error: could not compile `embuild` due to 7 previous errors
warning: build failed, waiting for other jobs to finish...

This is an error with embuild, not espflash
