rustup

Install, manage, and update Rust toolchains. Some subcommands, such as toolchain, target, update, etc. have their own usage documentation. More information: https://rust-lang.github.io/rustup.

• 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}} cargo build

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