rustup: renamed from rustup-init

• Have you followed the guidelines for contributing?
• Have you ensured that your commits follow the commit style guide?
• Have you checked that there aren't other open pull requests for the same formula update/change?
• Have you built your formula locally with HOMEBREW_NO_INSTALL_FROM_API=1 brew install --build-from-source <formula>, where <formula> is the name of the formula you're submitting?
• Is your test running fine brew test <formula>, where <formula> is the name of the formula you're submitting?
• Does your build pass brew audit --strict <formula> (after doing HOMEBREW_NO_INSTALL_FROM_API=1 brew install --build-from-source <formula>)? If this is a new formula, does it pass brew audit --new <formula>?

With #177582, rustup-init now provides the full rustup installation (so using the rustup-init installer is no longer necessary)

Rename the formula to just rustup to reflect these changes (which also hopefully gives users some indication of these changes)

[chenrui333]

maybe split the PR into two one depends_on rustup for test, one depends_on rustup

[branchvincent]

What are you thinking? But the audit will fail if this isn't renamed all in one PR:

$ brew audit rustfmt
rustfmt
  * Can't find dependency 'rustup-int'.
Error: 1 problem in 1 formula detected.

[chenrui333]

aha, that sounds about right. Yeah, the transition for such thing is not easy.

[chenrui333]

also, this might need a long build label

[branchvincent]

Gonna follow #165649 instead so this can be a syntax-only PR: add rustup as a new formula first, migrate existing dependents to call rustup directly instead of rustup-init, and then update formula_renames.json here

[AurevoirXavier]

Shit. This breaks all my CIs.

Such an important update without any warning and migration test.

@AurevoirXavier this was tested and was expected to be backwards compatible. The only noticeable change is we now link rustup on PATH by default

can you share more about what exactly is breaking for you (i.e. a reproducible example)?

EDIT: Looks like this is from brew update moving the formulae to keg-only but not triggering our post_install method (which is where we ensure rustup-init remains linked). Created #178322 which will fix this for brew upgrade. In your case, a short-term workaround would be brew update && brew reinstall rustup (and of course long-term, it'll be resolved when github updates their image to include these changes)

I think there were already some links to this PR. Such as edgedb/edgedb#7590, hack-ink/AiR@3583c95. Please take a look.
