I'm using the unstable features of rustfmt which is the sole reason I use the nightly Rust.
Can I adjust the toolchain so that I only use nightly rustfmt while the rest is stable?

I know you can just manually run cargo +nightly fmt.

it also installs the whole nightly toolchain right?

You need to install the toolchain first. +<TOOLCHAIN> is just a way to override the toolchain for the specific action.
