## What it is
Rustup is the official toolchain installer and version manager for the Rust programming language. It installs and switches between stable, beta, and nightly Rust compilers, keeps them updated, and simplifies cross-compilation with prebuilt standard libraries.

## Use cases
- install rust on my machine
- switch between rust stable and nightly toolchains
- keep rust compiler up to date
- set up cross-compilation targets for rust
- manage multiple rust toolchain versions per project
- install rust on windows

## When to choose
- you are starting a new Rust project and need the compiler
- you need to work across projects pinned to different Rust versions
- you want to track nightly Rust features or run rustfmt/clippy components
- you need to cross-compile Rust for other platforms

## When to avoid
- you only need a Rust compiler bundled by your OS package manager and never switch versions
- you are managing Rust in a hermetic Bazel or Nix build that provisions its own toolchains

## Facets
- artifact type: cli-tool
- maturity: stable
- function: package-manager, build-tool, developer-tools, cli
- domain: developer-tools, programming-languages, cross-platform
- platform: windows, bsd, cli, cross-platform
- tags: rustlang, toolchain, installer, version-management, cross-compilation, command-line, linux, macos
