rust-lang/rustup — The Rust toolchain installer

Description and use

rustup is the official installer and version manager for the Rust programming language, allowing developers to easily download, configure, and switch between multiple Rust toolchains and associated components. It streamlines setup across platforms, handles updates, and provides commands for managing nightly, beta, and stable releases, making Rust development more accessible and reproducible.

Problem

rust-lang/rustup may be useful when its README and activity match a concrete workflow.

Outcome
