Setting for which toolchain to use

[smmalis37]

It would be nice to have a vscode extension setting for which installed rust toolchain should be used for all commands (stable, beta, nightly, a specific nightly, etc). Currently I have one project I'm working on that requires nightly for unstable features, but all of my others don't and I would prefer them to be on stable. It would be nice to have a setting for this so i could set it globally to stable and then override it to nightly in just that one project.

This is handled by rustup override command

I wasn't aware of this feature of rustup. That's cool!

This is the only place I read about it, and I feel it should be documented somewhere. Could this information be added to the manual?

@lnicola Yes, that's why I tried adding this to my config file:

    "rust-analyzer.runnables.cargoExtraArgs": [
        "+beta-msvc"
    ]

I also tried this:

   "rust-analyzer.runnables.overrideCargo": "cargo +beta-msvc"

However, when I tried that rust-analyzer gave me an error that indicated that this setting didn't take effect, leading me to assume that wasn't possible.

It's good to know that rustup can affect the cargo command on a per-directory basis, and I think it would be good to call it out here.

But that's described on the same page (https://rust-lang.github.io/rustup/overrides.html#directory-overrides). Anyway, I guess we could take a PR with a mention of this, even though it's out-of-scope for RA.
