The moral of today's lesson is that platform-portable bytecode has its advantages. JVMs are designed to compile and link even big applications to native code in seconds.

Unless you have a specific reason for managing Rust with Homebrew, I would definitely recommend switching to Rustup as it will download pre-built binaries rather than building from source. It also allows you to maintain and switch between different toolchains (e.g. stable vs nightly) and will update all of your toolchain components (e.g. rust_analyzer). On my MBP, `rustup update` takes ~3 mins to update two toolchains and a bunch of components I've installed.
