==>Pouring rustup-1.28.2.arm64_sequoia.bottle.tar.gz
==>Caveats
To initialize `rustup`, set a default toolchain:
rustup default stable
If you have `rust` installed, ensure you have "$(brew --prefix rustup)/bin"
before "$(brew --prefix)/bin" in your $PATH:
https://rust-lang.github.io/rustup/installation/already-installed-rust.html
rustup is keg-only, which means it was not symlinked into /opt/homebrew,
because it conflicts with rust.
If you need to have rustup first in your PATH, run:
echo 'export PATH="/opt/homebrew/opt/rustup/bin:$PATH"' >> ~/.zshrc
==>Summary
🍺 /opt/homebrew/Cellar/rustup/1.28.2: 27 files, 11.5MB
==>Running `brew cleanup rustup`...
Disable this behaviour by setting `HOMEBREW_NO_INSTALL_CLEANUP=1`.
Hide these hints with `HOMEBREW_NO_ENV_HINTS=1` (see `man brew`).
==>Caveats
zsh completions have been installed to:
/opt/homebrew/opt/rustup/share/zsh/site-functions
