Include Rustup Toolchain File

I use stable on other projects and it's an annoyance to rustup default nightly to mess around with Clippy and then have to switch back to stable. Can Clippy include a rustup toolchain file specifying nightly?

I don't see a downside to this since Clippy doesn't work on any other toolchain. I know I can also just set a rustup directory override but this seems like it can save everyone some hassle.

I didn't know that existed! The only problem I see with that is that you might prefer an override for a specific nightly instead of the latest. Do you know what happens if there is an override and a toolchain file?

The override takes precedence.

The full rules are over here. The rustup guys thought of everything.
