I had a hunch that Warp would be the answer when I started reading. I hit the same issue and worked around it the same way (boxing). My build times also went from 1-2 minutes down to a couple seconds. Generally speaking, most of my Rust work has been reasonably fast on modern hardware. Waiting 3-5 seconds for incremental builds isn't a big deal. I've only seen the excessive compile times with cold starts or in weird edge cases like the Warp issue.
