rustup

Rust toolchain installer.

Install, manage, and update Rust toolchains.

• Install the nightly toolchain for your system:

rustup install nightly

• Switch the default toolchain to nightly so that the `cargo` and `rustc` commands will use it:

rustup default nightly

• Use the nightly toolchain when inside the current project, but leave global settings unchanged:

rustup override set nightly

• Update all toolchains:

rustup update

• List installed toolchains:

rustup show

• Run cargo build with a certain toolchain:

rustup run {toolchain_name} cargo build

• Open the local rust documentation in the default web browser:

rustup doc
