Research direction

Start with the installer entry point at https://sh.rustup.rs and locate the logic that adds . "$HOME/.cargo/env" to ~/.profile. Reproduce the documented installation on macOS, then verify that the setup uses ~/.zprofile there while behavior on other platforms remains unchanged.

Description

bug

Verification

I searched for recent similar issues at https://github.com/rust-lang/rustup/issues?q=is%3Aissue and found no duplicates.
I am on the latest version of Rustup according to https://github.com/rust-lang/rustup/tags and am still able to reproduce my issue.

Problem

Running the installation script from the rust-lang.org install page on macOS adds . "$HOME/.cargo/env" to ~/.profile rather than ~/.zprofile where it needs to be to work.

Steps

Run curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
Restart Terminal, without manually sourcing the ~/.profile file.
Rust will not run until ~/.profile is manually sourced or . "$HOME/.cargo/env" is moved to ~/.zprofile.

Possible Solution(s)

Have the setup script add . "$HOME/.cargo/env" to ~/.zprofile instead of ~/.profile on macOS specifically.
