Also great question about using nightly, we're using a shared-generics flag that requires nightly (and speeds up build times).
We're working on making this more configurable to enable / disable what features you want.
Yeah, I skipped over this, considering that most people doing rust dev will likely have some kind of SSD.
I didn't look into how you went about doing this, but one thing that I'd like is to be able to move the target/ directory on a ram disk, or, generally, out of the source root [0]. If Fleet were able to do this transparently, it would be really great.

[0] I know it's possible to define an external directory, but it applies to all projects, and it's not what I want, because shared crates would go overwrite each other.
The reason I'm asking is that I use the IntelliJ plugin for Rust dev which is kind of clunky and only understands a few commands as being "build", so it doesn't show the build window.
