In their own words
rustup
rustup installs Rust from its official release channels and manages the toolchains and supporting components developers use. It can switch among stable, beta, and nightly compilers, keep toolchains updated, and install specific versions or dated releases. For cross-compilation, add a target’s standard library with `rustup target add`; Android builds also require the Android NDK and usually a linker. rustup manages official channels, archived releases, alternate hosts, and local builds. It installs command proxies for tools including rustc, rustdoc, Cargo, rust-analyzer, Clippy, and Miri. Component availability varies by release and toolchain, especially for nightly. Installation uses a shell script on Unix and rustup-init.exe on Windows. Downloads use HTTPS, but download signatures are not yet validated. rustup is free and open source, with a free plan. Its listed supported platforms are Linux, macOS, and Windows; the installer also runs on FreeBSD, NetBSD, Solaris, and illumos.
