What rustup is
rustup installs Rust toolchains from official release channels and manages their updates. It lets users switch among stable, beta, and nightly compilers, with multiple toolchains available through command proxies in `~/.cargo/bin`. Projects can specify a toolchain in a `rust-toolchain.toml` or `rust-toolchain` file; users can also choose one through command-line shorthand, an environment variable, a directory override, or a global default. For cross-compilation, `rustup target add` installs another target’s Rust standard library, though additional tools such as a linker or the Android NDK may be needed. The installer site lists Windows, Linux, macOS, FreeBSD, NetBSD, Solaris, and illumos as supported systems. Windows’ default toolchain uses the MSVC ABI and requires Visual Studio for its linker and libraries. rustup generates completions for Bash, Fish, Zsh, and PowerShell. It is free and open source, under either Apache License 2.0 or MIT. Nightly toolchains may fail to build or lack non-default components for a particular date and target.
Good
- Manages stable, beta, and nightly toolchains.
- Projects can pin a toolchain with a file.
- Installs Rust standard library components for other targets.
- Generates completions for four named shells.
- Free and open source.
Watch out
- Nightly toolchains may fail or lack components.
- Cross-compilation may need extra tools.
- Windows’ default toolchain requires Visual Studio.
Who it suits
rustup suits Rust developers who need to install, update, or switch toolchains, including projects that pin a specific toolchain. It can also help users set up cross-compilation targets, provided they have any additional required tools.
Verdict
rustup centralizes Rust toolchain installation, updates, and selection, with project-level pinning and target support. Account for the nightly caveat and any extra cross-compilation requirements.
