Install and Manage Rust Toolchains with rustup
rustup⮳ is a toolchain multiplexer. It installs, manages, and upgrades versions of the rust compiler rustc⮳, the Rust package manager cargo⮳, the Rust linter clippy⮳, the Rust code formatter rustfmt⮳, etc.
More precisely, rustup⮳ can install and manage multiple Rust toolchains and presents them all through a single set of tools installed to ~/.cargo/bin. The rustc⮳ and cargo⮳ executables installed e.g. in ~/.cargo/bin are proxies that delegate to the real toolchain.
rustup⮳ is similar to Python's pyenv⮳ or Node's nvm⮳.
