About
rustup installs Rust from official release channels and manages the toolchains developers use. It can switch among stable, beta, and nightly compilers, keep them updated, and install specific versions or dated releases. For cross-compilation, rustup installs a target platform’s standard library with `rustup target add`; Android builds also require the Android NDK and usually a linker. It manages official and archived toolchains, alternate hosts, and local builds, and installs proxies for tools including rustc, Cargo, rustdoc, rust-analyzer, Clippy, and Miri. Component availability differs across releases and toolchains, particularly for nightly. Installation uses a shell script on Unix and rustup-init.exe on Windows, where Visual Studio prerequisites may also be needed. Downloads use HTTPS, but signatures are not yet validated. The official Rust project is free and licensed under Apache License 2.0 or MIT. It runs on Windows, Linux, and macOS, among other listed systems.
Who it is for
rustup suits Rust developers who need to install, update, switch, or pin toolchains across Linux, macOS, or Windows. It also supports cross-compilation workflows and linking local toolchain builds.
What is good
- Switches among stable, beta, and nightly toolchains.
- Can install specific versions or dated releases.
- Adds target standard libraries for cross-compilation.
- Manages local builds alongside official toolchains.
- Provides proxies for rustc, Cargo, and rust-analyzer.
What to know first
- Component availability varies by release and toolchain.
- Nightly toolchains may fail to build or lack components.
- Download signatures are not yet validated.
- Android cross-compilation also requires the NDK and usually a linker.
Verdict
rustup is a focused toolchain manager for Rust development, with support for version switching, components, and cross-compilation targets. Keep component gaps and the lack of signature validation in mind when planning installations.
