There are pre-built binaries for most used operating system platforms, but you can also compile and build from the source code yourself.
On your RockPi’s Linux command line console type
#install tools and modules sudo apt-get install pkg-config #install Rust language curl https://sh.rustup.rs -sSf | sh # select 1 default # configure your users shell path for Rust # To get started you need Cargo's bin directory ($HOME/.cargo/bin) in your PATH # environment variable. Next time you log in this will be done automatically. # To configure your current shell run source $HOME/.cargo/env
From here, clone the repository, compile the RUST code and copy the resulting binaries into a subfolder which will contain your node from hereon forth.
