Install Rust

Video demonstrates steps described below.

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Environment

Once Rust is installed environment has to be modified, so binaries can be found.

source $HOME/.cargo/env

Content of $HOME/.cargo/env looks like:

#!/bin/sh
# rustup shell setup
# affix colons on either side of $PATH to simplify matching
case ":${PATH}:" in
    *:"$HOME/.cargo/bin":*)
        ;;
    *)
        # Prepending path in case a system-installed rustc needs to be overridden
        export PATH="$HOME/.cargo/bin:$PATH"
        ;;
esac

Update Rust

rustup update nightly && rustup update stable
rustup target add wasm32-unknown-unknown --toolchain nightly
